Abstract
Y2CaA14SiO12 garnet-type glass-ceramic was obtained by heat-treatment of the bulk glass with corresponding composition, which fabricated by aerodynamic levitation coupled with a laser heating system. The crystallization kinetics of the glass was investigated via Differential Scanning Calorimetry (DSC). The effects of heat-treatment temperature on the phase, microstructure, mechanical and optical properties of the Y2CaA14SiO12 garnet-type glass-ceramic were also systemically studied. The crystallization mechanism of this Y2CaA14SiO12 glass is three-dimensional growth followed with surface and inner nucleation. With the increasing of heat-treatment temperature, the density and hardness increased, while transparency declined as a result of rapid grain growth.
