Abstract :
We report the effects of the addition of PFW on the decrease of the sintering temperature and the improvement of dielectric properties at microwave frequencies of the PCZ ceramic system. It was found that an addition of Pb(Fe2/3W1/3)O3 promotes the grain growth, the solid solution between the Pb-based perovskite and the Ca-based perovskite and a decrease of the sintering temperature. We found that 0.05Pb(Fe2/3W1/3)O3-0.95(Pb xCa1-x)ZrO3 ceramic can be sintered at less than 1250°C. The dielectric properties of this compound are better than those of the (PbxCa1-x)ZrO3 ceramic system
