Effect of B2O3 on Microwave Dielectric Properties of Ca[(Li1/3Nb2/3)0.92Zr0.08]O3−δ−0.05TiO2 Ceramics
The effects of B2O3 on the sinter ability and microwave dielectric properties of Ca [(Li1/3Nb2/3)0.92Zr0.08]O3−δ−0.05TiO2 (CLNZ−0.05TiO2) ceramics were investigated. B2O3 doping can effectively reduce sintering temperature by 150~200 °C. The temperature coefficient of resonator frequency τf increased with an increase of B2O3 content and sintering temperature. When B2O3 of 2.5 wt % were added, the optimum microwave dielectric properties: εr =34.2, Qf =15680GHz and τf = − 4.7×10−6/°C were obtained at the sintering temperature of 950 °C.
