Popis: BaTiO3 and Ba(Ti,Zr)O3 dielectric powders have been prepared from submicrometer BaCO3, TiO2, and ZrO2. By use of submicrometer BaCO3 the intermediate formation of Ba2TiO4 second phase can be widely suppressed. Monophase perovskites of BaTiO3 were already formed at 900°C and Ba(Ti,Zr)O3 at 1050°C. Aggregates of very small subgrains could be easily disintegrated to particle sizes
