Abstract The effect of ZnO doping on the crystal phase, microstructure and properties of calcium-borosilicate glass-ceramics (CBS) were studied. The Rietveld refinement method was used to calculate the crystallinity and crystal phase content. The analysis results showed that ZnO doping improved the crystallization of CBS system and promoted the formation of quartz and wollastonite. Moreover, ZnO significantly promoted the sintering densification and the mechanical properties of CBS glass-ceramics. When ZnO doping amount was 8wt%, the bending strength and Young's modulus were 207.9 MPa and 82.9 GPa, the dielectric constant was 5.75, the dielectric loss was 7.1×10-4, and the thermal expansion coefficient was 9.62×10-6/℃.
