摘要
本文以易析晶玻璃系统为对象,分析比较了各种析晶动力学判据,认为玻璃析晶峰值温度的析晶速率常数k(T_p)=R_oexp(-E/RT_p)是一个具有普适意义的析晶动力学判据.用这一判据可以方便,准确地确定各玻璃系统中玻璃析晶的难易,寻求稳定的玻璃成份.
By analyzing and comparing various criteria for crystallization dynamics based on crystallizabk glass systems,this paper concludes that the constant of crystallization rate k(T_p) = K_oexp(-E/ RT_p) at the peak temperature of glass crystallization is an universal criterion for crystallization dynamics. With this criterion, the easiness of glass crystallization in glass systems can be easily and accurately determined so as to find a stable glass composition.
