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 ...
Calcium phosphates are white solids of nutritional value [2] and are found in many living organisms, e.g., bone mineral and tooth enamel. [3] In milk, it exists in a colloidal form in micelles bound to casein protein with magnesium , zinc , and citrate –collectively referred to as colloidal calcium phosphate (CCP). [ 4 ]
The hydroxyapatite nanocrystal suspension can be prepared by a wet chemical precipitation reaction following the reaction equation below: [11] 10 Ca(OH) 2 + 6 H 3 PO 4 → Ca 10 (PO 4) 6 (OH) 2 + 18 H 2 O. The ability to synthetically replicate hydroxyapatite has invaluable clinical implications, especially in dentistry.
Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 4 2– anion involves the removal of two protons from phosphoric acid, H 3 PO 4.

Calcium phosphide (CP) is the inorganic compound with the formula Ca 3 P 2. It is one of several phosphides of calcium, being described as the salt-like material composed of Ca 2+ and P 3−. Other, more exotic calcium phosphides have the formula CaP / Ca 2 P 2, CaP 3, and Ca 5 P 8. Ca 3 P 2 has the
