【摘要】 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Ga36.5Sb63.5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。更多还原

【Abstract】 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 Ga36.5Sb63.5 melt,which divides the viscosity-temperature curve into two segments,i.e.low temperature segment and high temperature segment.According to the microstructure feature of the melts,the experimental results were discussed.更多还原
