Numerical calculus and experiment for crystallization process of li2o - al2o3 - sio - p2o5 system glass indicated : size of crystallization grain can be controlled by forming residual glass phase with high melting point , and by this way we got transparent glass - ceramic 并依據理論分析的受控模型獲得了小晶粒的透明微晶玻璃。討論了通過主晶相和殘余玻璃相的膨脹系數估算析晶量的方法。
