There is a critical point in all glass phase separation boundaries.The phasetransition at this point belongs to continuous phase transition.By the discussionin this paper,it has been known that the phase separation in binary glass systemscan be described by the modern continuous phase transition theory.The equationsfor the immiscible curves at the two sides of the neighborhood of the critical pointare:(x′-x_c)/x_c=A[(T_c-T)/T_c]~(1/3),(x′-x_c)/x_c=A′[(T_c-T)/T_c](1/3).Here A andA′are universal constants of immiscible curves.In this paper,the fitting results ofA and A′from Li_2O-SiO_2,Na_2O-SiO_2,BaO-SiO_2 system′s experimental data ofphase separation are A=-1.8305:A′=2.3551.The corresponding calculated curvesfit the experimental data very well.Further research will be done for getting moreaccurate universal A and A′.

In this study, the second phase droplets in glass phase separation have been determined byTEM technique in which powdered specimen is used.

本文详细讨论了利用粉末电镜法研究玻璃分相中第二相颗粒在母体相中的存在关系。对电镜所反映出的分相玻璃中第二相粒子的尺度、分布等进行了分析。利用统计的方法并考虑了玻璃分相中会出现大小不同的国球及椭球形颗粒,导出了适用于第二相颗粒为国球或椭球时通用的计算实际颗粒平均粒度、分布等的新定量公式。全部公式的处理现已编制了程序并在计算机上通过。实际玻璃分相的有关数据可直接利用电镜照片上测得的数值经由计算机处理而得到,使用较为方便。
