The reciprocal CuInS2+2CdSe⇔CuInSe2+2CdS system—Part II: Liquid–solid equilibria in the system

The phase equlibria in the reciprocal system CuInSe2+2CdS⇔CuInS2+2CdSe were investigated by differential thermal and X-ray phase analysis. The phase diagrams of a series of vertical sections, a liquidus surface projection and a spatial phase diagram were constructed. It was established that the addition of cadmium chalcogenides leads to the stabilization of the cubic modifications of the ternary compounds, which form a continuous solid solution series, at the annealing temperatures. The boundaries of the solid solutions were determined by the change of the unit cell parameters; the isothermal sections at 620 and 870 K were constructed.
