摘要：
Using Li2O-B2O3-SiO2 (LBS) glass and LiF as a liquid phase sintering additive, the effects of it on the microstructure and properties of 16CaO-9Li(2)O-12Sm(2)O(3)-63TiO(2) (CLST) ceramics were investigated. The results indicated that the compound sintering aids of LBS glass and LiF reduced the sintering temperature of CLST from 1300 degrees C to 950 degrees C. Compared with the sample doped single LBS glass, the optimum dielectric properties, Kr=81, Tan delta=0.0073 could be obtained when the CLST ceramic samples doped 3 wt% LBS glass and 0.25 wt% LiF were sintered at 950 degrees C for 3 h.
