采用淬火法研究CaF2-Al2O3体系的相平衡关系,并作出相图。氟化钙与氧化铝构成简单共熔二元系,共熔点是1290±5°,7分子%Al2O3。氟化钙与氧化铝的固溶体(Pascal)以及CaAl2O3F2与CaAl10O15F2化合物(Günther等)在本工作中均未能证实。

The phase equilibrium relationships in the system CaF2-Al2O3 have been examined by the quenching method, from which the phase diagram was plotted. Calcium fluoride-alumina is a simple binary system with one eutectic point at 7 mole percent of alumina and a temperature of 1290°.
