【Abstract】 The purpose of present work was to avoid check cracks on the surface of glass-ceramics in MgO-Al2O3-SiO2 system which usually appeared during manufacturing process, so as to improve the quality and enhance the rate of finished products. The results of DTA, X-ray diffraction and TEM examination show that the crystalline process of glass-ceramics depends upon the annealing process, so an optimum annealing schedule is ona of the important measure to avoid surface check cracks of glass-ceramics.更多还原
