Abstract: To modify glass-ceramic bond, ZnO-Al₂O₃-B₂O₃-SiO₂ (ZABS) glass was prepared by conventional melting method. The influence of boron-silicon ratio and sintering process on its thermal and mechanical properties, as well as crystallizing behavior was discussed. The microstructure of the glass and its wettability on diamond abrasive were studied. Results show that with increased boron content, the thermal expansion coefficient of glass increases and its thermal resistance decreases, while bending strength first increases and then decreases. Too much boron will make the bond cover the grain entirely, which is bad for grinding. It is also found that with increased silicon content, the viscosity of glass increases, thus leading to poor wettability to grains. Too much silicon leads to poor bending strength. In conclusion, the best boron-silicon ratio of ZABS glass is 1:1 in weight, and the optimized heat treatment is 710℃ for 2 h. The glass would have a thermal expansion coefficient of 5.132 7×10^-6℃^-1 and a bending strength of 78 MPa, as well as good wettability to grains.
