摘要 以Li2O-Al2O3-SiO2三元系(LAS)微晶玻璃为研究对象,采用DTA、XRD等测试技术研究了不同Li2O含量LAS玻璃的核化行为,分析了Li取代对LAS玻璃核化行为的影响。研究结果表明,随着Li含量的降低,LAS系玻璃的相转变温度、析晶峰温度逐步增大,最佳核化温度逐渐升高,最佳核化时间没有明显的变化。 The nucleation behavior of Li2O-Al2O3-SiO2 (LAS) glass by replacement of Li ion was studied by DTA and XRD. The results show that the phase transition temperature, crystallization peak temperature and nucleation temperature increase with the decrease of Li contents, but the nucleation time does not change too much.
