【摘要】 在初晶相为鳞石英的平板玻璃中加入千分之几的P₂O₅后对析晶性能的影响与初晶相为硅灰石的平板玻璃是不同的。但它们仍遵循多元相平衡关系。透射电镜观察和电阻率测量表明,加入微量P₂O₅能促进平板玻璃的分相。XPS测量结果进一步揭示了由于加入微量P₂O₅所引起平板玻璃结构上的一些变化。更多还原

【Abstract】 The effect of addition of P₂O₅ in a few thousandths on the devitrification behavior of plate glass with primary phase of tridymite is different from that with primary phase of wollastonite. Such effect still follows phase equilibrium relationship of multicomponents. Based on TEM observation and measurement of electrical resistivity, it indicates that phase separation of plate glass may be improved by adding a minor amount of p₂O₅·Through XPS measurement, it is shown further that such addition will cause a certain change in structure of plate glass.更多还原
