摘要：
The initial stages of the formation of CdAs2-ZnAs2 solid solutions are analyzed in terms of crystalchemical energetics. Given that the bond enthalpies decrease in the order H (Zn-As)< H (Cd-As)< H (As-As), it is concluded that, most likely, CdAs2-based solid solutions are substitutional and ZnAs2-based solid solutions are interstitial, and that the thermochemical stability of the substitutional solid solutions is higher than that of CdAs2 . The conclusions drawn from crystal-chemical analysis correlate with the reported x-ray diffraction, chemical analysis, resistivity, and Hall data for the solid solutions.
