Abstract

The crystallization kinetics of Li₂O-Al₂O₃-GeO₂-P₂O₅ (LAGP) glass fabricated via the conventional melt-quenching method was studied by differential scanning calorimetry (DSC) under nonisothermal condition at different heating rates. The activation energy of glass transition E_g is 634.4 kJ/mol, indicating that LAGP glass is easy to crystallize at an elevated temperature. The activation energy of crystallization E _c and Avrami index n obtained from Matusita’s model are 442.01 kJ/mol and 1.7, respectively. The value of n reveals that bulk crystallization predominates slightly over surface crystallization during crystallization process. LAGP glass-ceramics after different heat treatments have the same crystalline phases determined as major phase LiGe₂(PO₄)₃, with AlPO₄ and GeO₂ as their impurity phases.
