在Li_2O-Al_2O_3-SiO_2系中分别制备了含三种复合晶核剂(TiO_2+ 、ZrO_2+ 、P_2O_5)的玻璃和微晶玻璃。采用差示扫描量热仪、X射线衍射仪、拉曼光谱、傅立叶变换红外光谱和扫描电子显微镜等手段研究了P_2O_5含量对微晶玻璃结晶机理和微观结构的影响。同时讨论了结构和组成对热膨胀系数、透光率、维氏硬度、密度、弯曲强度和化学稳定性的影响。结果表明，P_2O_5可能通过形成AlPO_4，促进ZrTiO_4的析出，从而促进晶核和晶化过程。随着P_2O_5含量的增加(<5 wt%)，晶化温度升高对晶粒长大过程的促进作用逐渐增强。尤其是当P2O5含量为5 wt%时，P5样品的晶粒度最小，性能最好，并且存在一个相对较低的温度和较宽的温度范围，可以使P5样品的晶粒度基本保持不变。
The glasses and glass-ceramics in Li2O-Al2O3-SiO2system containing three complex nucleating agents (TiO2+ ZrO2+ P2O5) were prepared respectively. The effects of P2O5content on crystallization mechanism and microstructure were researched by means of Differential Scanning Calorimetry, X-Ray Diffraction, Raman Spectra, Fourier Transform Infrared and Scanning Election Microscopy. Simultaneously, the effects of structure and composition on thermal expansion coefficient, transmittance, Vickers hardness, density, bending strength, and chemical stability were also discussed. The results indicated that P2O5can promote the nucleation and crystallization process by forming AlPO4and accelerating the precipitation of ZrTiO4. With the increase of P2O5content (less 5 wt%), the promoting effect of elevated crystallization temperature on the process of grain grown enhanced gradually. Especially when P2O5content is 5 wt%, the sample have the smallest crystals and the best performance, and there is a relatively low temperature and wide temperature range where could keep the grain size of P5 samples almost unchanged.
