Abstract—The quasi-binary join Si-ZnAs₂ of the system Zn–Si–As was studied by physicochemical methods.
The congruently melting compound ZnSiAs₂ and eutectics Si + ZnSiAs₂ and ZnSiAs₂ ZnAs₂ are formed
along this join. The composition of the eutectic Si + ZnSiAs₂ is 90 mol % ZnAs₂ and 10 mol % Si; T_m = 630°C.
The composition of the eutectic ZnSiAs₂ + Si is 55 mol % Si and 45 mol % ZnAs₂. The component solubilities
in ZnSiAs₂ do not exceed 1 mol %.
