摘要
Phase equilibria in the Cu–Cu2Se–As were investigated by differential thermal analysis and X-ray powder diffraction analysis. Informative plots describing this system were constructed, viz., the polythermal sections Cu0.667Se0.333–As, Cu0.667Se0.333–Cu0.735As0.265, and Cu0.8Se0.2–As, the isothermal section of the phase diagram at 300 K, and the projection of the liquidus surface. The obtained results differ from the published data in length of fields of primary crystallization of phases and in coordinates of a number of invariant equilibrium points.
