| 摘 要： | 3BaO·3B2O3·2Ge02是BaO-B2O3-GeO2三元系中的一个三元化合物。本文用差热分析法对3BaO·3B2O3·2GeO2非晶态晶化过程进行了研究,非晶的晶化温度随颗粒度减小而下降。用等温晶化法和峰值位移法测定了不同颗粒度的晶化激活能,非晶颗粒度越小,晶化激活能越大。关键词：

| Abstract: | 3BaO·3B2O3·2GeO2 is a new compound in the ternary system BaO-B2O3-GeO2. Its crystallization process has been studied by means of thermoanalysis method. The temperature of crystallization decreases distinctly with decrease of the grain size. The activation energy of crystallization of the amorphous material with different grain size have been determined by means of the isothermal crystallization method or thermal peak shift method. The smaller the grain size is, the greater the activation energy of crystallization. |
