【Abstract】 The glass-ceramics of CaO-MgO-Fe2O3-Al2O3-SiO2 slag was prepared. Crystallizationkinetics parameter and activation energy of the system were investigated by the kinetics theory andDTA technique. The crystallization mechanism of two-dimensional crystal growth and m=n=2was determmed.The activation energy calculated was 272.6 kJ’mol-1. The microstructure ob-tained by the SEM technique indicated that the mechanism of crystal growth-is in good agreementwith the result predicted.更多还原
