Phase equilibria in the quasi-ternary system Cu2Te-CdTe-In2Te3 were investigated by differential thermal and x-ray phase analyses methods. Five vertical sections CuInTe2-CdTe, 'Cu1.5In0.5Te1.5'-CdTe, CuInTe2-CdIn2Te4, CuIn5Te8-CdTe, CuIn5Te8-CdIn2Te4 were constructed. System triangulation was performed, and the boundaries of six single-phase fields at 670 K were determined, which are the solid solution ranges of the components and the intermediate phases of the system. Liquidus surface projection was investigated, and we have identified a monovariant eutectic process L a double dagger dagger beta + delta, and three nonvariant processes L-U + eta a double dagger dagger delta + epsilon, beta + delta a double dagger dagger alpha + zeta, delta a double dagger dagger gamma + epsilon + eta at 965 K, 847 and 690 K, respectively, that take place in the system.
