| Abstract | (Zr0.8Sn0.2)TiO4 ceramics with additives of ZnO, CuO, Bi2O3 and MnCO3 were prepared by the conventional mixed oxide route. They were characterized by TG/DTA, SEM, EDS and a network analyzer. Microwave properties of (Zr0.8Sn0.2)TiO4 ceramics were investigated as a function of the amount of additives. The optimal values of dielectric constant er, quality factors Q*f and temperature coefficient of resonant frequency tf reached 35, 51000 GHz and 26 ppm/°C respectively with 2.0 wt% MnCO3. Specimens with additives of ZnO, CuO and Bi2O3 had microwave properties of er = 35 ~ 39, Q*f = 9000 ~ 35000 GHz and tf = 15~40 ppm/°C. |
