The evaporation of sodium tellurite glass in low gravity is explored and the formation and growth processes of teo2 microspheres are explained . the size of teo2 microspheres from low gravity is much larger than that from ground experiments and it is affected mainly by the temperature of melt in the heating coil and the duration time of vapor cloud during drop experiments 探索了微重力对亚碲酸钠玻璃熔体气化的影响,分析了微重力下由于玻璃熔体气化而生成teo _ 2玻璃微球的过程,解释了微重力下形成的微球尺寸远远大于摘要地面模拟实验所得微球的原因。
