Abstract: The nucleation behavior of Li2O- Al2O3- SiO2 (LAS) glas s by replacement of Li ion was s tudied by DTA and XRD. The results show that the phase trans ition temperature, crys tallization peak temperature and nucleation temperature increase with the decrease of Li contents , but the nucleation time does not change too much.
