Abstract

An experimental study is performed of the high-temperature region of the phase diagram of the Ca3(PO4)2–CaNaPO4–CaKPO4 system. The compositions of the phase fields at 1200°C are determined. It is shown that the region of tricalcium composition at the given temperature consists of two single-phase regions: high-temperature α-Ca3(PO4)2 and low-temperature β-Ca3(PO4)2. The upper temperatures of the existence of fields of the phase triangle section at 1200°C are determined.

Ca3(PO4)2-CaKPO4-CaNaPO4体系高温区的实验研究

摘要

对Ca 3 (PO 4 ) 2 –CaNaPO 4 –CaKPO 4体系相图的高温区域进行了实验研究。确定了 1200°C 下的相场组成。结果表明,给定温度下的三钙组成区由两个单相区组成:高温α-Ca 3 (PO 4 ) 2和低温β-Ca 3 (PO 4 ) 2。确定了 1200°C 时相三角形截面存在场的上限温度。
