  • 4 Citations


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 %.
