The possibility of the formation of a solid solution in the Sr1−xLaxSn1−xCoxO3 system has been explored. Single-phase solid solution forms in the compositions for x⩽0.10. All single-phase solid solution compositions have a cubic structure similar to SrSnO3. The dielectric behaviour of these solid solution compositions has been studied as a function of temperature and frequency. The frequency dependence of dielectric constant and dielectric loss in these materials indicates that space charge polarization contributes significantly to their observed dielectric parameters. Microstructural studies show the presence of well-faceted grains. The average grain size in these samples is small.
