CaO—SiO2—Ga2O3系的熔点测定

用试样变形法测定了ＣａＯ－ＳｉＯ２－Ｇａ２Ｏ３三元系的熔点。对实验数据经过适当的数学处理，描绘出用质量百分浓度和用摩尔分数表示的坐标系中的等熔点曲线。实验设计上采用了优化处理。

DETERMINATION OF MELTING POINT OF CaO-SiO_2-Ga_2O_3 SYSTEM

This paper lays a foundation in the investigation into the characteristics of Ga2O3 containing slag. The isomelting-point contour of the ternary system of CaO-SiO2-Ga2O3 was measured. The phase analysis has not been carried out in the test since our purpose is to provide a temperature dependent melting range for future research rather than draw a phase diagram of the system. In the design of the test,minimum testing points were used in an attempt to get more information and reduce some variables to simplify the mathematical processing by taking advantage of the characteristics of the ternary system coordinate and the principle of thermodynamics.
