Influence of the Isomorphism of the Solid Solutions of Barium Strontium Titanates on Segnetoceramic Properties

Abstract

This scientific paper gives the research data relating to the opportunity for the varying of the properties of segnetoceramic materials due to hetero-and isovalent substitutions in the cation sublattices of solid solutions by varying the parameters of crystalline lattice and basic material characteristics at maintaining monophasicity. For the materials based on barium and strontium titanates the admixtures were used that enabled the variation of the cation substitution of barium, strontium and titanium. The parameters for the stable synthesis of the similar materials of a preset composition were defined experimentally. The compositions for segnetoceramic materials with appropriate performance characteristics have been developed.
