Such information is also available from Evonik Industries AG, Product Safety Department. We recommend to read carefully the material safety data sheet prior to the use of our product.Packaging and storageOur products are inert and extremely stable chemically. However, due to their high specific surface area, they can absorb moisture and volatile organic compounds from the surrounding atmosphere. Therefore, we recommend to store the products in sealed containers in a dry, cool place, and removed from volatile organic substances. Even if a product is stored under these conditions, after a longer period it can still pick up ambient moisture over time, which could lead to its exceeding the specified moisture content. For this reason, our recommended use­by date is 24 months after date of manufacture. Product more than 24 months old should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.ACEMATT TS 100 is a fumed silica that is not surface treated.

Coating formulations containing ACEMATT TS 100 show outstanding resistance against household chemicals.ACEMATT TS 100 improves flow behavior and increases storage stability in powder coatings.Thermal, untreated matting agent.Average agglomerate particle size (median TEM): 4 µm The chemical compound silicon dioxide, also known as silica (from the Latin silex),is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity.[1] Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. It is a principal component of most types of glass and substances such as concrete. Silica is the most abundant mineral in the earth’s crust.ACEMATT TS 100 features excellent matting efficiency and transparency. Because of the unique manufactoring process, it is particularly suitable for systems wich are difficult to matt, for water-borne dispersion coatings and for finish coatings. Use of ACEMATT TS 100 may provide coatings with outstanding resistance to household chemicals. Thanks to the high purity and the resulting low conductivity ACEMATT TS 100 is ideal for use in sensitive coating systems. ACEMATT TS 100 improves flow behavior and the storage stability of powder coatings.Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula SiO2, most commonly found in nature as quartz and in various living organisms.[5][6] In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product. Notable examples include fused quartz, fumed silica, silica gel, and aerogels. It is used in structural materials, microelectronics (as an electrical insulator), and as components in the food and pharmaceutical industries.Inhaling finely divided crystalline silica is toxic and can lead to severe inflammation of the lung tissue, silicosis, bronchitis, lung cancer, and systemic autoimmune diseases, such as lupus and rheumatoid arthritis. Inhalation of amorphous silicon dioxide, in high doses, leads to non-permanent short-term inflammation, where all effects heal.[7]In the majority of silicates, the silicon atom shows tetrahedral coordination, with four oxygen atoms surrounding a central Si atom. The most common example is seen in the quartz polymorphs. It is a 3 dimensional network solid in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms.For example, in the unit cell of α-quartz, the central tetrahedron shares all four of its corner O atoms, the two face-centered tetrahedra share two of their corner O atoms, and the four edge-centered tetrahedra share just one of their O atoms with other SiO4 tetrahedra. This leaves a net average of 12 out of 24 total vertices for that portion of the seven SiO4 tetrahedra that are considered to be a part of the unit cell for silica (see 3-D Unit Cell).SiO2 has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. With the exception of stishovite and fibrous silica, all of the crystalline forms involve tetrahedral SiO4 units linked together by shared vertices. Silicon–oxygen bond lengths vary between the various crystal forms; for example in α-quartz the bond length is 161 pm, whereas in α-tridymite it is in the range 154–171 pm. The Si-O-Si angle also varies between a low value of 140° in α-tridymite, up to 180° in β-tridymite. In α-quartz, the Si-O-Si angle is 144°.[9]Fibrous silica has a structure similar to that of SiS2 with chains of edge-sharing SiO4 tetrahedra. Stishovite, the higher-pressure form, in contrast, has a rutile-like structure where silicon is 6-coordinate. The density of stishovite is 4.287 g/cm3, which compares to α-quartz, the densest of the low-pressure forms, which has a density of 2.648 g/cm3.[10] The difference in density can be ascribed to the increase in coordination as the six shortest Si-O bond lengths in stishovite (four Si-O bond lengths of 176 pm and two others of 181 pm) are greater than the Si-O bond length (161 pm) in α-quartz.[11] The change in the coordination increases the ionicity of the Si-O bond.[12] More importantly, any deviations from these standard parameters constitute microstructural differences or variations, which represent an approach to an amorphous, vitreous, or glassy solid.The only stable form under normal conditions is alpha quartz, in which crystalline silicon dioxide is usually encountered. In nature, impurities in crystalline α-quartz can give rise to colors (see list). The high-temperature minerals, cristobalite and tridymite, have both lower densities and indices of refraction than quartz. Since the composition is identical, the reason for the discrepancies must be in the increased spacing in the high-temperature minerals. As is common with many substances, the higher the temperature, the farther apart the atoms are, due to the increased vibration energy.[citation needed]The transformation from α-quartz to beta-quartz takes place abruptly at 573 °C. Since the transformation is accompanied by a significant change in volume, it can easily induce fracturing of ceramics or rocks passing through this temperature limit.[13]The high-pressure minerals, seifertite, stishovite, and coesite, though, have higher densities and indices of refraction than quartz. This is probably due to the intense compression of the atoms occurring during their formation, resulting in more condensed structure.[14]Faujasite silica is another form of crystalline silica. It is obtained by dealumination of a low-sodium, ultra-stable Y zeolite with combined acid and thermal treatment. The resulting product contains over 99% silica, and has high crystallinity and surface area (over 800 m2/g). Faujasite-silica has very high thermal and acid stability. For example, it maintains a high degree of long-range molecular order or crystallinity even after boiling in concentrated hydrochloric acid.[15]Molten silica exhibits several peculiar physical characteristics that are similar to those observed in liquid water: negative temperature expansion, density maximum at temperatures ~5000 °C, and a heat capacity minimum.[16] Its density decreases from 2.08 g/cm3 at 1950 °C to 2.03 g/cm3 at 2200 °C.[17]Molecular SiO2 with a linear structure is produced when molecular silicon monoxide, SiO, is condensed in an argon matrix cooled with helium along with oxygen atoms generated by microwave discharge. Dimeric silicon dioxide, (SiO2)2 has been prepared by reacting O2 with matrix isolated dimeric silicon monoxide, (Si2O2). In dimeric silicon dioxide there are two oxygen atoms bridging between the silicon atoms with an Si-O-Si angle of 94° and bond length of 164.6 pm and the terminal Si-O bond length is 150.2 pm. The Si-O bond length is 148.3 pm, which compares with the length of 161 pm in α-quartz. The bond energy is estimated at 621.7 kJ/mol.[18]Even though it is poorly soluble, silica occurs in many plants. Plant materials with high silica phytolith content appear to be of importance to grazing animals, from chewing insects to ungulates. Silica accelerates tooth wear, and high levels of silica in plants frequently eaten by herbivores may have developed as a defense mechanism against predation.[21][22]Silica is also the primary component of rice husk ash, which is used, for example, in filtration and cement manufacturing.For well over a billion years, silicification in and by cells has been common in the biological world. In the modern world it occurs in bacteria, single-celled organisms, plants, and animals (invertebrates and vertebrates). Prominent examples include:Tests or frustules (i.e. shells) of diatoms, Radiolaria, and testate amoebae.Silica phytoliths in the cells of many plants, including Equisetaceae, practically all grasses, and a wide range of dicotyledons.The spicules forming the skeleton of many sponges.Crystalline minerals formed in the physiological environment often show exceptional physical properties (e.g., strength, hardness, fracture toughness) and tend to form hierarchical structures that exhibit microstructural order over a range of scales. The minerals are crystallized from an environment that is undersaturated with respect to silicon, and under conditions of neutral pH and low temperature (0–40 °C).Formation of the mineral may occur either within the cell wall of an organism (such as with phytoliths), or outside the cell wall, as typically happens with tests. Specific biochemical reactions exist for mineral deposition. Such reactions include those that involve lipids, proteins, and carbohydrates.It is unclear in what ways silica is important in the nutrition of animals. This field of research is challenging because silica is ubiquitous and in most circumstances dissolves in trace quantities only. All the same it certainly does occur in the living body, creating the challenge of creating silica-free controls for purposes of research. This makes it difficult to be sure when the silica present has had operative beneficial effects, and when its presence is coincidental, or even harmful. The current consensus is that it certainly seems important in the growth, strength, and management of many connective tissues. This is true not only for hard connective tissues such as bone and tooth but possibly in the biochemistry of the subcellular enzyme-containing structures as well.[23]Structural use About 95% of the commercial use of silicon dioxide (sand) occurs in the construction industry, e.g. for the production of concrete (Portland cement concrete).[19]Certain deposits of silica sand, with desirable particle size and shape and desirable clay and other mineral content, were important for sand casting of metallic products.[24] The high melting point of silica enables it to be used in such applications such as iron casting; modern sand casting sometimes uses other minerals for other reasons.Crystalline silica is used in hydraulic fracturing of formations which contain tight oil and shale gas.Precursor to glass and silicon Silica is the primary ingredient in the production of most glass. As other minerals are melted with silica, the principle of Freezing Point Depression lowers the melting point of the mixture and increases fluidity. The glass transition temperature of pure SiO2 is about 1475 K.[26] When molten silicon dioxide SiO2 is rapidly cooled, it does not crystallize, but solidifies as a glass. Because of this, most ceramic glazes have silica as the main ingredient.The structural geometry of silicon and oxygen in glass is similar to that in quartz and most other crystalline forms of silicon and oxygen with silicon surrounded by regular tetrahedra of oxygen centers. The difference between the glass and crystalline forms arises from the connectivity of the tetrahedral units: Although there is no long range periodicity in the glassy network ordering remains at length scales well beyond the SiO bond length. One example of this ordering is the preference to form rings of 6-tetrahedra.[27]The majority of optical fibers for telecommunication are also made from silica. It is a primary raw material for many ceramics such as earthenware, stoneware, and porcelain.Silicon dioxide is used to produce elemental silicon. The process involves carbothermic reduction in an electric arc furnace:Food, cosmetic, and pharmaceutical applications Silica, either colloidal, precipitated, or pyrogenic fumed, is a common additive in food production. It is used primarily as a flow or anti-caking agent in powdered foods such as spices and non-dairy coffee creamer, or powders to be formed into pharmaceutical tablets.[29] It can adsorb water in hygroscopic applications. Colloidal silica is used as a fining agent for wine, beer, and juice, with the E number reference E551.In cosmetics, silica is useful for its light-diffusing properties[30] and natural absorbency.Diatomaceous earth, a mined product, has been used in food and cosmetics for centuries. It consists of the silica shells of microscopic diatoms; in a less processed form it was sold as “tooth powder”.[citation needed] Manufactured or mined hydrated silica is used as the hard abrasive in toothpaste.

Silika fitolitleri. Süngerler Fizyolojik ortamda oluan kristalli mineraller genellikle istisnai fiziksel özellikler gösterir (örnein, mukavemet, sertlik, krlma tokluu) ve bir dizi ölçekte mikroyapsal düzen sergileyen hiyerarik yaplar oluturma eilimindedir. Mineraller, silikona göre yetersiz doymu bir ortamdan ve nötr pH ve düük scaklk (0-40 ° C) koullar altnda kristalize edilir.Mineralin oluumu, bir organizmann hücre duvar içinde (örn. fitolitler) veya tipik olarak testlerde olduu gibi hücre duvarnn dnda. Mineral birikimi için özel biyokimyasal reaksiyonlar mevcuttur. Bu tür reaksiyonlar arasnda lipidler, proteinler ve karbonhidratlar yer alr. Hayvanlarn beslenmesinde silikann hangi yönlerden önemli olduu belirsizdir.Bu aratrma alan zordur çünkü silika her yerde bulunur ve çou durumda yalnzca eser miktarlarda çözünür. Ayn ey kesinlikle canl vücutta meydana gelir ve aratrma amacyla silika içermeyen kontroller oluturma zorluunu yaratr. Bu, mevcut silikann ne zaman ilevsel yararl etkilere sahip olduundan ve varlnn tesadüfi ve hatta zararl olduunda emin olmay zorlatrr. Mevcut fikir birlii, birçok ba dokusunun büyümesi, gücü ve yönetiminde kesinlikle önemli göründüü yönündedir. Bu sadece kemik ve di gibi sert ba dokular için deil, ayn zamanda muhtemelen hücre alt enzim içeren yaplarn biyokimyas için de geçerlidir. [23] Yapsal kullanm Silikon dioksitin (kum) ticari kullanmnn yaklak% 95’i inaat sektörü, örnein Beton üretimi için (Portland çimento betonu) [19] Arzu edilen parçack boyutuna ve ekline ve istenen kil ve dier mineral içeriine sahip belirli silis kumu birikintileri, metalik ürünlerin kum dökümü için önemliydi. [24] Silisin yüksek erime noktas, demir döküm gibi uygulamalarda kullanlmasn salar; modern kum dökümünde bazen baka nedenlerle dier mineraller kullanlr. Kristalin silika, sk petrol ve eyl gaz içeren oluumlarn hidrolik krlmasnda kullanlr.Cam ve silikonun öncüsü Silika, çou camn üretiminde birincil bileendir. Dier mineraller silika ile eritildii için Donma Noktas Alçalmas prensibi karmn erime noktasn düürür ve akkanl artrr. Saf SiO2’nin cam geçi scakl yaklak 1475 K’dir. [26] Erimi silikon dioksit SiO2 hzla soutulduunda kristallemez, ancak bir cam olarak katlar. Bu nedenle, çou seramik sr ana bileen olarak silikaya sahiptir. Camdaki silikon ve oksijenin yapsal geometrisi, kuvars ve dier birçok kristalin silikon ve oksijen formlar ve oksijen merkezlerinin düzenli tetrahedralar ile çevrili olana benzer. Cam ve kristal formlar arasndaki fark, dört yüzlü birimlerin balanabilirliinden kaynaklanmaktadr: Cams a sralamasnda uzun menzilli periyodiklik olmamasna ramen, SiO ba uzunluunun çok ötesinde uzunluk ölçeklerinde kalr. Bu sralamaya bir örnek, 6-dörtyüzlü halkalar oluturma tercihidir. [27] Telekomünikasyon için optik fiberlerin çou da silikadan yaplmtr. Çanak çömlek, ta ve porselen gibi birçok seramik için birincil hammaddedir.Silikon dioksit elemental silikon üretiminde kullanlr. Proses, bir elektrik ark ocanda karotermik indirgeme içerir: Gda, kozmetik ve farmasötik uygulamalar Koloidal, çökeltilmi veya pirojenik tütsülenmi silika, gda üretiminde yaygn bir katk maddesidir. Öncelikle baharat ve süt ürünü olmayan kahve kremas gibi toz gdalarda veya farmasötik tabletler haline getirilecek tozlarda ak veya topaklanmay önleyici ajan olarak kullanlr. [29] Higroskopik uygulamalarda suyu adsorbe edebilir. Kolloidal silika, E551 referans numarasyla arap, bira ve meyve suyu için bir inceltici ajan olarak kullanlr. Kozmetiklerde silika, yayma özellikleri [30] ve doal emicilii için kullanldr. yüzyllardr gda ve kozmetikte kullanlmaktadr. Mikroskobik diatomlarn silika kabuklarndan oluur; daha az ilenmi formda “di tozu” olarak satld. [kaynak belirtilmeli] Di macununda sert andrc olarak imal edilmi veya çkarlm hidratlanm silika kullanlr.
