摘要：

The phase diagram of the ZnGeAs2-CdGeAs2 system was constructed using a set of physicochemical analysis methods (X-ray powder diffraction, differential thermal, and microstructural analyses). It was shown that there is a continuous series of solid solutions Zn (x) Cd1 - x GeAs2 in the system at temperatures above 600A degrees C. At temperatures below 600A degrees C, there is a significant phase separation region. The solubility at room temperature on the side of ZnGeAs2 does not exceed 12 mol % CdGeAs2, and that on the side of CdGeAs2 is no more than 16 mol % ZnGeAs2. The change in the crystal lattice parameters of the solid solutions within these concentration ranges obeys Vegard's law, which is indicative of the mutual replacement of Zn and Cd in the cation sublattice of the compounds ZnGeAs2 and CdGeAs2.
