In this work hydroxyapatite was precipitated from calcium hydroxide and phosphoric acid. Calcium hydroxide forms in addition to hydroxyapatite in samples with calcium to phosphorus ratio more than the stoichiometric one (Ca/P = 1.67). The effect of changing the pH of the precipitation solution was ...
Calcium phosphate is usually prepared by reacting calcium hydroxide (Ca(OH)₂) with phosphoric acid (H₃PO₄) or by heating a mixture of calcium carbonate (CaCO₃) and ammonium phosphate ((NH₄)₃PO₄). Calcium phosphate is generally considered non-toxic and is safe for use in...

Calcium phosphates are usually manufactured by reacting very pure phosphoric acid with calcium hydroxide, Ca(OH)2obtained from limestone, in stoichiometric ratio in aqueous suspension followed by drying at a temperature that will allow the correct hydration state to be achieved. After drying, the coar...
