Phase equilibria in the ZnGeAs2-CdGeAs2 system

The phase equilibria in the ZnGeAs2-CdGeAs2 system were investigated by X-ray, DTA, EDXRF, microstructure observations and SEM. The solid solutions are present in all range of concentrations above 440 °С. Below this temperature a decay region of solid solution of Zn1−xCdxGeAs2 is observed in the range of concentrations x = 0.19-0.92 at room temperature. The investigation of the system was obstructed by liquation and segregation processes occurring during the synthesis.
