Abstract
Abstract: Phase equilibria in the FeSe–Ga2Se3–In2Se3 system were studied by differential thermal analysis and X-ray powder diffraction analysis. A number of polythermal sections, the isothermal section at 1000 K, and the projection of the liquidus surface of the phase diagram were constructed. It was determined that this system is quasi-ternary, and that the liquidus surface comprises the fields of primary crystallization of six phases. The types and coordinates of invariant and monovariant equilibria were found. Wide regions of solid solutions based on binary and ternary compounds (FeGa2Se4, FeIn2Se4) were revealed, being of interest as magnetic materials.
