Abstract :
The processing of modified lead titanate powders by hydrothermal synthesis and the fabrication of ceramics from the powder produced are described. Results of powder and ceramic characterization are presented and related to results for ceramics prepared by conventional mixed oxides. The powders obtained have submicron particle size. Ceramics fabricated from these powders have higher densities and better piezoelectric properties than those of a similar composition prepared by the mixed oxides route. The ceramics offer fine grain size and properties suitable for high-frequency single-element devices
