Abstract
SrTiO3-BiCrO3 ceramics were prepared by solid-state reactions. The materials were single-phase by x-ray diffraction and had a cubic perovskite structure up to 70 mol % BiCrO3. Low-frequency conductivity measurements revealed semiconducting behavior of the solid solutions. Dielectric measurements in the microwave range revealed flat maxima of a relaxation nature in the temperature dependences of the dielectric permittivity and tan δ for the samples containing 30 and 40 mol % BiCrO3. The solid solutions were found to exhibit relatively high dielectric losses in the microwave range.
