摘要：

An experimental study is performed of the high-temperature region of the phase diagram of the Ca-3(PO4)(2)-CaNaPO4-CaKPO4 system. The compositions of the phase fields at 1200 degrees C are determined. It is shown that the region of tricalcium composition at the given temperature consists of two single-phase regions: high-temperature alpha-Ca-3(PO4)(2) and low-temperature beta-Ca-3(PO4)(2). The upper temperatures of the existence of fields of the phase triangle section at 1200 degrees C are determined.
