The crystalline composition, microstructure and mechanical properties of experimental lithium disilicate glass-ceramic and IPS e.max Press were compared. No obvious difference in mechanical properties and crystalline composition was found between these two materials.

对比分析了实验二硅酸锂玻璃陶瓷和IPS e.max Press玻璃陶瓷的晶相组成，微观结构和机械性能，探讨了微观结构与性能的关系，并对牙科二硅酸锂玻璃陶瓷的自增韧机制进行了分析。

It was concluded that P2O5 was an effective nucleating agent for this glass system. The nucleation density of this glass system was too low to form tiny crystal after heat-treatment, when it contained no P2O5, and the major crystal phase was lithium silicate. Adding P2O5 resulted in major tiny crystal phase of lithium disilicate after heat-treatment.

结果发现P2O5是该玻璃体系的有效成核剂，未添加P2O5的玻璃体系成核密度低，热处理后不能形成微晶体，且主晶相为硅酸锂；添加P2O5使玻璃在热处理后形成以二硅酸锂为主晶相的微晶玻璃。
