Popis: Fine-crystalline barium titanate was synthesized by a new method using supercritical water and examined as a raw material for dielectric ceramics preparation by semidry pressing and further high-temperature sintering. The nature of temporary technological binder utilized at the stage of pressing significantly affected the structural, mechanical and electro-physical properties of BaTiO3 ceramics. Ceramics prepared from BaTiO3 powder synthesized in supercritical water possessed necessary applied characteristics: the dielectric permittivity as high as 2819 and loss tangent as low as 0.012.
