## Abstract The dielectric permittivity ฯต of BaTiO~3~ single crystals __versus__ the temperature __T__ at different hydrostatic pressure ฯ, and ฯต(ฯ) at different __T__, was measured. The highest ฯ achieved was 12 800 kg/cm^2^, between 22 ยฐC and 180 ยฐC. At ฯ < 3500 kg/cm^2^, the Curie point __T__~__
BSTO dielectric ceramic was prepared from SrTiO 3 and BaTiO 3 powders synthesized by hydrothermal method, as well as from Ba 0.6 Sr 0.4 TiO 3 powder synthesized by conventional solid-state reaction. The former can be sintered at a relatively low temperature of 1120 โข C. Characterization by SEM showe
