Character of Tricalcium Phosphate:
Tricalcium phosphate is white amorphous powder, odorless, tasteless, and stable in the air.
Tricalcium phosphate is insoluble in ethanol and acetone, slightly soluble in water, soluble in dilute hydrochloric acid and nitric acid.
Preparation of Tricalcium Phosphate:
Tricalcium phosphate is produced commercially by treating hydroxyapatite with phosphoric acid and slaked lime.
Tricalcium phosphate cannot be precipitated directly from aqueous solution.
Typically double decomposition reactions are employed, involving a soluble phosphate and calcium salts, e.g. (NH4)2HPO4 + Ca(NO3)2.
Tricalcium phosphate is performed under carefully controlled pH conditions.
The precipitate will either be “amorphous Tricalcium phosphate”, ATCP, or calcium deficient hydroxyapatite, CDHA, Ca9(HPO4)(PO4)5(OH), (note CDHA is sometimes termed apatitic calcium triphosphate).
Crystalline Tricalcium phosphate can be obtained by calcining the precipitate.
β-Ca3(PO4)2 is generally formed, higher temperatures are required to produce α-Ca3(PO4)2.
An alternative to the wet procedure entails heating a mixture of a calcium pyrophosphate and calcium carbonate:
CaCO3 + Ca2P2O7 → Ca3(PO4)2 + CO2
Natural Occurrence of Tricalcium Phosphate:
Tricalcium phosphate is found in nature as a rock in Morocco, Israel, Philippines, Egypt, and Kola (Russia) and in smaller quantities in some other countries.
The natural form of Tricalcium phosphate is not completely pure, and there are some other components like sand and lime which can change the composition.
In terms of P2O5, most calcium phosphate rocks have a content of 30% to 40% P2O5 in weight.
Structure of Β-, Α- And Α′- Ca3(Po4)2 Polymorphs of Tricalcium Phosphate:
Tricalcium phosphate has three recognised polymorphs, the rhombohedral β form (shown above), and two high temperature forms, monoclinic α and hexagonal α′.
β-Tricalcium phosphate has a crystallographic density of 3.066 g cm−3 while the high temperature forms are less dense, α-Tricalcium phosphate has a density of 2.866 g cm−3 and α′-Tricalcium phosphate has a density of 2.702 g cm−3
All forms have complex structures consisting of tetrahedral phosphate centers linked through oxygen to the calcium ions.
The high temperature forms each have two types of columns, one containing only calcium ions and the other both calcium and phosphate.
There are differences in chemical and biological properties between the β and α forms, the α form is more soluble and biodegradable.
Both forms are available commercially and are present in formulations used in medical and dental applications
