The sintering behavior and microwave dielectric properties of the 16CaO-9Li2O-12Sm2O3-63TiO2 (abbreviated CLST) ceramics doped by small amount of LBS (Li2O-B2O3-SiO2) glass were investigated in this paper. The adding of LBS glass improved the densification of the CLST ceramics and the sintering temperature of the CLST ceramics had been efficiently lowered to 1000°C. Especially, the 10wt.% LBS doped CLST sintered at 1000°C for 3h has optimum microwave dielectric properties of Kr=69, Q×f=2846GHz, and TCF=9.7ppm/°C, indicating that it could be a suitable candidate for LTCC applications.
