差示扫描量热法（DSC）研究已经进行，试图解释Cu x Ge 15 Te 85-x玻璃的热结晶行为的成分依赖。可以看出，这些玻璃在加热时表现为单玻璃转变和单阶段结晶。玻璃化转变温度、结晶温度和结晶活化能在成分x = 5附近均有异常。在x = 5处观察到的热性能异常可能与刚性渗透有关。
Differential scanning calorimetric (DSC) studies have been carried out in an attempt to explain the composition dependence of the thermal crystallization behaviour of Cu x Ge 15 Te 85-x 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.
