Effect of Compound Additives of Li2O-B2O3-SiO2 Glass and LiF on the Properties of CaO-Li2O-Sm2O3-TiO2 Ceramics
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-9Li2O-12Sm2O3-63TiO2（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 °C to 950°C. Compared with the sample doped single LBS glass, the optimum dielectric properties, Kr=81, Tanδ=0.0073 could be obtained when the CLST ceramic samples doped 3 wt% LBS glass and 0.25 wt% LiF were sintered at 950°C for 3 h.
