利用熔体黏度仪系统研究了不同成分Ga-Sb熔体的黏度变化规律.结果表明,Ga-Sb熔体的黏度总体趋势是随温度的降低而增大,黏度变化曲线基本呈指数变化.其中Ga_(36.5)Sb_(63.5)熔体黏度随温度的变化在830℃左右出现突变,将黏度曲线分成低温区和高温区两部分.根据该熔体结构变化的特点,对有关试验结果进行了分析讨论.

Viscosity change rules of Ga-Sb melts with different composition were studied by a viscometer. The results show that the viscosity of Ga-Sb melts increases generally with the temperature decreasing, and the change curves have the feature of exponential change. It is distinct that there is abnormal discontinuous change at 830 ℃ for Ga_(36.5)Sb_(63.5) melt, which divides the viscosity-temperature curve int otwo segments, i.e. low temperature segment and high temperature segment. According to the microstructure feature of the melts, the experimental results were discussed.
