In this paper,(Zr,Sn)TiO 4 system high-frequency ceramics for multilayer ceramic capacitors (MLCC) was prepared at intermediate-temperature (1150℃) by general electric ceramics technology.The addition of CuO,ZnO,BaCO 3,SrCO 3 and G(Glass) to the system lowered the sintering temperature and improved the dielectric properties.The effects of dopants on the dielectric properties of the system were investigated.The prepared ceramic material has excellent dielectric properties at 1MHz as follows:ε≈38,Q=1/tanδ≥10 4,ρ V≥10 11Ω·m,α C=(0±30)×10 -4/℃.
