摘要：

Fine powders of BaTiO3 and BaTi0·8Zr0·2O3 were prepared by hydrothermal synthesis from the hydroxides of barium, titanium and zirconium. The shape of the products was spherical (diameter = 0·1 μm)and the particle size distribution was very narrow. The ceramics made from these materials indicate superior sintering and dielectric properties. The green bodies were sintered at 1200°C (100-150°C lower than the powders made by the calcination method and oxalate method). BaTiO3 sintered body indicated a high K value of 4300 at 20°C, a good biassing property and a low dissipation factor. © 1990.
