摘要：
Microwave dielectric ceramics 0.4(Ca0.61Nd0.26)TiO3-0.6(Li0.5Sm0.5)TiO3 (CNLST) were prepared by doping CuO as the liquid-phase sintering aid. The effects of CuO on the microstructures and dielectric properties were investigated. Due to the liquid-phase effect, the sintering temperature of CNLST with 0.5wt.% CuO addition has be effectively reduced to 1100 degrees C, while good microwave dielectric properties of epsilon(r)=83.4, Q center dot f=3880GHz, tau(f) =2.1ppm/degrees C.
