    Abstract

    The crystallization kinetics of lithium aluminum silicate Li2OAl2O3SiO2ZrO2P2O5 transparent glassceramics was analyzed by using the classical equation (JohnsonMehlAvrami). The influence of crystallization temperature on the crystallization behavior of glass was studied by DSC, XRD and SEM. The results show that Li2Si2O5 and Li2SiO3 precipitate at lower initial crystallization temperature. With the increase of crystallization temperature, the main crystal phase changes to LiAlSi4O10, Li2SiO3 disappears and the crystal size decreases, and the transmittance of glassceramics increases from 89.3% to 90.6% at 550 nm. The activation energies of crystallization of Li2Si2O5 and LiAlSi4O10 are calculated by Kissinger method to be 349.5 kJ/mol and 184.2 kJ/mol, and the average crystal growth indices are 3.05 and 1.42, respectively.
