Abstract: | Chemical Vapor Transport of Solid Solutions. 3 Chemical Transport of MnO/ZnO, FeO/ZnO, and CoO/ZnO Mixed Crystals By means of chemical vapor transport using HCl as transport agent (950 → 750 °C) it is possible to prepare solid solutions of MnO, FeO, and CoO in the lattice of ZnO (wurtzite type). Preparation of solutions of ZnO in MnO, FeO resp. CoO however was possible only in the case of FeO. Single crystals up to 10 mm length could be prepared by this way. Lattice parameters have been determined. UV-Vis spectra have been measured and been discussed. Mössbauer spectra of the FeO containining compound have been recorded. |
