Paper Title:
Effects of ZnO-Bi2O3-B2O3-SiO2 Glass Additive on Dielectric Properties of CaO-Li2O-Sm2O3-TiO2 Microwave Dielectric Ceramics
  Abstract

The effects of ZnO-Bi2O3-B2O3-SiO2(ZBBS) glass addition on the sintering behavior, crystalline phase, microstructure and dielectric properties of 16CaO-9Li2O-12Sm2O3-63TiO2(CLST) ceramics were investigated. The results show that ZBBS glass can effectively decrease the sintering temperature of CLST ceramics to 1 000 °C by liquid phase sintering. With the increase of ZBBS content, the second phase,Sm2Ti2O7 is found and increase, which causes the dielectric constant and dielectric loss of CLST decrease. The temperature coefficient of the resonance frequency shifts to positive. The optimum dielectric properties of r = 71, Tan = 0.006, TCF= 5×10-6/°C were obtained in 10wt% LBS glass-doped CLST ceramics sintered at 1 000 °C for 3 h.
