用热重、差热分析和X射线衍射法研究了无定形磷酸钙（ACP）的脱水和热变化。ACP保留水高达约773 K。脱水后，立即通过点燃从具有高度过饱和度的溶液中沉淀的ACP获得高温形式的磷酸钙，α -Ca 3（PO 4）2（α -TCP）。本文还研究了由ACP热结晶α-TCP的动力学。
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.
