Abstract / Full Text

Lanthanum–strontium gallate–ferrites are thought of as perspective electrode materials. A series of La1 –x Sr x Fe1 –y Ga y O3 – δ (x = 0.2–0.5; y = 0–0.4) compositions is synthesized by self-propagating high-temperature synthesis. The solid solutions’ existence domain is identified. The linear expansion thermal coefficient and the electric conductivity of the materials in the form of ceramics are studied for single-phase samples.
