Based on the formation of an ideal solid solution between CdTe and HgTe, the thermodynamic analysis of the complex Hg 1−x Cd x Te‐iodine chemical vapor transport system could be somewhat simplified because the source material composition was at the Te‐rich boundary of the homogeneity range of Hg 0·8 Cd 0·2 Te. This led to the development of a first order approximation model for the prediction of diffusion limited mass transport rates. The agreement between computed and experimental (vertical, stabilizing conditions) mass transport rates is quite satisfactory.
