Studies on the Chemical Vapor Transport in the System ZnS/ZnSe By means of chemical transport reactions homogeneous ionic mixed crystals with well defined compositions can be prepared in a simple way. This is shown at the example of ZnS/ZnSe‐mixed crystals. ZnS 1−x Se x ‐mixed crystals can be prepared by chemical vapour transport in the temperature gradient 1000 → 900 °C using iodine as transport agent. A thermodynamic model is presented to calculate the thermodynamic stability of ionic mixed phases and possible enrichment effects during the vapor transport. The results are compared with experimental fundings and well known transport models.
