Abstract

The dielectric properties of (1 – x)BaTiO3–xSrTiO3 (x = 0.0; 0.25; 0.50; 0.75 and 1.00) mixed nanocomposites, obtained by sintering the initial components at a temperature of 1273 K for 5 hours, have been studied within the temperature range of 100–500 K. X-ray analysis, performed at room temperature, showed that the composites are formed by BaTiO3 (P4mm) and SrTiO3 (Pm-3m) crystallites and do not contain Ba(1 – х)SrхTiO3 solid solutions. A decrease in the temperatures of the Amm2 → P4mm → Pm-3m phase transitions in barium titanate particles with an increase in the SrTiO3 concentration in the composite was found.
