Features of barium and strontium titanates and ferrites synthesized from a melt in a solar furnace

A ferro ceramic material based on titanate and a magnetic material based on barium and strontium ferrite obtained by furnace-based melt synthesis have been studied. A nonmonotonic characteristic feature of doping barium titanate with iron oxide Fe2O3, which consists in constructing the permittivity of BaTiO3, has been revealed. The optimal concentration of doping of iron oxide is determined - 6 mol.%, beyond which saturation of the dependence curves of the dielectric properties of barium titanate is observed. It was revealed that barium and strontium ferrites exhibit high-temperature multiferroic properties.
