摘要：

Study of the system CaHPO4-KOH-H2O at 25 degrees C allowed determination of the precipitation fields of CaHPO4 and the apatite compounds KCaPO4. H2O and K4Ca(PO4)(2). 5H(2)O. 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.
