Experimental study of the ternary system Cd---Te---Zn

The ternary system Cd---Zn---Te has been studied by differential thermal analysis, differential scanning calorimetry and X-ray powder diffraction. A solid solution is observed between CdTe and ZnTe. At low temperature this quasi-binary section exhibits a miscibility gap. The liquid-liquid miscibility gap induced by the binary monotectic reaction extends within the ternary system and its boundary has been determined. The only ternary reaction existing in this system is a eutectic reaction at 265 °C and the corresponding composition is located in the very close neighbourhood of the binary eutectic Cd---Zn.
