The content of the irregular bigger drop phase approached to pyrope. It showed that the crystallization and phase separation mechanics of the glass was the nucleation-and-growth transformation and the crystallization is bulk crystallization. The activation energies of phase separation and crystallization were calculated by the modified Kissinger method, about 310.445 KJ/mol and 249.26 KJ/mol respectively. Using the aluminum hydroxide as the reference, we calibrated the phase separation exothermal enthalpy of the quenched and nucleation treated glass, ca
