HCID 24456Tricalcium Phosphate

Procedure

To a vigorously stirred calcium hydroxide suspension, an aqueous phosphoric acid solution was slowly added dropwise until the pH became 7 and the formed precipitate was calcined at 800° C. for 3 hours to obtain tricalcium phosphate, which was further ground by using a mortar and then passed through a sieve (average particle diameter: 45 μm) (calcium phosphate A).
