Abstract：The effects of ZnO-B2O3（ZB2） on the sintering behavior and microwave dielectric properties of （Ca0.254Li0.19Sm0.14）TiO3 ceramics were investigated. Results show that the relative densities of the specimens reach the maximum value when adding 3%ZB2 （mass percent）. The sintering temperature is lowered from 1 300 ℃ to 1 100 ℃ without degradation of the microwave dielectric properties. The （Ca0.254Li0.19Sm0.14 ）TiO3 ceramic with 3%ZB2 （mass percent） sintered at 1 100 ℃ for 3 h shows good microwave dielectric properties， which is[εr＝]108.2， [Qf＝]6 545 GHz， and[τf＝]6.5×10－6/℃， indicating that ZB2 is an effective sintering aid to improve the densification and microwave dielectric properties of （Ca0.254Li0.19Sm0.14）TiO3 ceramics.
