Study on Crystallization Kinetics of Li₂O-Al₂O₃-TiO₂-P₂O₅ Glass by Non-Isothermal Technique

Abstract:

The crystallization kinetics of Li₂O-Al₂O₃-TiO₂-P₂O₅ (LATP) glass was studied by differential scanning calorimeter (DSC) and X-ray diffraction (XRD) techniques. The results showed that DSC curves of LATP glass have a single glass transition temperature followed by one crystallization peak for β = 5 K/min and two crystallization temperatures T_p1 and T_p2 for β ≥ 10 K/min. The activation energies of crystallization obtained from Kissinger model of the first exothermal peak and the second exothermal peak of LATP glass are 251 kJ/mol and 310 kJ/mol, respectively. The Avrami exponents of the both crystallization peaks are approximately 3, indicating that the three-dimensional crystalline growth during its amorphous to crystalline transformation. LiTi₂(PO₄)₃ and unknown crystalline phases firstly form when the mother glass was annealed at 973 K. With increasing of annealing temperature, AlPO₄ phase appears.
