Crystallization kinetics of SiO2-MgO-3CaO-P2O5-Al2O3-ZrO2 glass
Abstract
The crystallization behaviour of SiO2–MgO–3CaO–P2O5–Al2O3–ZrO2 glass was studied using glass samples prepared by melting reagent grade SiO2, MgO, Ca5(PO4)3OH, P2O5, Al2O3 and ZrO2. DTA and XRD analysis revealed the crystallization of whitlockite, anorthite and baddeleyite phases. The crystallization kinetics was studied by applying the DTA measurements carried out at various heating rates. The activation energies of crystallization and viscous flow were measured as 209 kJ·mol –1 and 356 kJ·mol –1 , respectively. The resultant SiO2–MgO–3CaO–P2O5–Al2O3–ZrO2 glass-ceramics revealed very fine and homogenous microstructure.
