Crystallization Kinetics of Lithium Aluminum Silicate Transparent Glass-Ceramics

Abstract

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.

Key words: Li₂O-Al₂O₃-SiO₂-ZrO₂-P₂O₅, transparent glass-ceramics, crystallization kinetics, crystallization behavior, activation energy
