Abstract

Dehydration and thermal change in amorphous calcium phosphate (ACP) have been studied by thermogravimetry, differential thermal analysis and X‐ray diffractometry. ACP retained water up to about 773 K. Immediately after the dehydration, a high‐temperature form of calcium phosphate, α —Ca₃(PO₄)₂ (α ‐TCP), was obtained by ignition of ACP precipitated from the solution with a high degree of supersaturation. The kinetics of thermal crystallisation of α‐TCP from ACP were also studied.
