| Abstract: | The microwave dielectric properties and sintering performances of Li0.925Nb0.375Ti0.8O3 ceramics with B2O3 and ZnO additions were investigated. The results indicate that ZnO and B2O3 compound addition could lower the sintering temperature to 900 ℃. Addition of ZnO reduce the temperature coefficient of frequency to negative. The optimal addition is found to be 1%B2O3 and 4 %ZnO when sintered at 900 ℃ for 2 h, the microwave dielectric materials thus obtained have the dielectric properties : εr =59.5, Q·f =7 840 GHz, τf =0×10–6 ℃–1. |
