In this paper, the the micro crystallization behavior of MgO-SiO2-Al2O3-B2O3-KF glass-ceramics which was prepared by sintering and water quenching method was discussed. The study indicated that the compacts shrinkage of MgO-SiO2-Al2O3-B2O3-KF glass-ceramics were related to its vitrification and its component crystallization degree; about the density of sintered compacts, the higher the crystallization degree, the higher the dense it owns. The conclusion reached above is significant in dimension control to the produce process. In the samples when the proportion of ingredient was closer to the atomic ratio of mica crystal, the higher the micro crystallization degree of the glass-ceramics will be. When sintering temperatuer is 1000oC,the MgO-SiO2-Al2O3-B2O3-KF glass-ceramics begain to present the crystallization; when it achieves to 1050°C, the crystallization degree is highest; continue to increase the sintering temperature, the micro crystallization will be melted again.

The influences of B2O3/SiO2 ratio and different alkali earth metal oxides MO (M= Ba, Mg, Ca) on the crystallization behavior of B2O3-Al2O3-SiO2 (BAS) glass were investigated by means of DSC, XRD and SEM. With the reduction of B2O3/SiO2 ratio, the crystallization activation energy increases at first and then decreases, reaching the minimum value of 375.4 kJ·mol-1 when the B2O3/SiO2 ratio is 2.2. The crystalline indices (n) are all more than 4, which indicates that the glass is in bulk crystallization. When the glass was heated to 800°C, the primary precipitated crystalline phase was Al4B2O9. With the increase of temperature up to 1100°C, Al18B4O33 and Al5BO9 appeared and became the major crystalline phases in BAS glass-ceramics.
