Abstract

Study of the system CaHPO4-KOH-H2O at 25°C allowed determination of the precipitation fields of CaHPO4and the apatite compounds KCaPO4·H2O and K4Ca(PO4)2·5H2O. The solid products were studied and identified by X-ray analysis. The water ratio is of great importance in the preparation of the starting mixture; it affects the nature of the compounds obtained after equilibrium.
