Abstract: Polymeric Precursor Method has become an important method for the preparation of microwave dielectric ceramics. In this paper, ZnTiO₃ powders have been prepared as examples, and then the effects of the pH value, the molar ratio of  EG to CA, and the molar ratio of CA to metallic ion on the synthesis of ZnTiO₃ crystalloid have been investigated. When the pH of the solvent is 5~6, a light yellow gel was obtained; when the molar ration of EG to CA is 2, the precursor resin is porous sponge; when the molar ration of CA to metallic ion is 2, the quality of the ZnTiO₃ powders prepared from the precursor is optimized.
