差示扫描量热（DSC）研究试图解释玻璃热结晶行为的成分依赖性。可以看出，这些玻璃在加热时表现出单一玻璃化转变和单阶段结晶。发现玻璃化转变温度、结晶温度和结晶活化能均在组成 x = 5 附近表现出异常。在 x = 5 处观察到的热性能异常可能与刚性渗滤相关。
Differential scanning calorimetric (DSC) studies have been carried out in an attempt to explain the composition dependence of the thermal crystallization behaviour of glasses. It is seen that these glasses exhibit a single glass transition and single-stage crystallization on heating. The glass transition temperature, crystallization temperature and the activation energy for crystallization are each found to exhibit an anomaly at around the composition x = 5. The anomalies observed in the thermal properties at x = 5 can be associated with rigidity percolation.
