Heterogeneous doping of sulfide-conducting phases based on calcium and barium thiolanthanates

Possibility of increasing the main functional property, the electrical conductivity in the known solid ionic salts with the conductivity of sulfur ions, by preparing composite mixtures with a semiconductor dopant is considered. The sulfide semi-product BaSm2S4 has been synthesized by using ceramic and chemical technology, as well as dopant ZrS2 and composite mixtures (100–x)BaSm2S4-x mol.% ZrS2 in a wide range of compositions. The study of the morphology and phase composition in the composite mixtures has revealed an ambiguous nature of the phase formation. Influence of the method for obtaining the oxide precursor on the electrical conductivity of a metacomposite based on barium thiosamarate has been investigated. The best compositional effect is achieved for metacomposites with ceramic prehistory. It is noted that in the resulting heterogeneous mixture, the sulfidic nature of the ionic salt conductivity is preserved.
