Resumo

The formation of metastable Cd3Ge2As4 was established using a set of physicochemical analysis methods. The annealing of this compound at temperatures ≥450°C was shown to lead to the formation of the stable binary eutectic Cd3As2–СdGeAs2 and ternary eutectic Cd3As2–СdGeAs2–CdAs2 with the following composition (at %): Cd, 42.20; Ge, 15.69; As, 42.11; and Cd, 42.70; Ge, 15.06; As, 42.24, respectively.
