Chemischer Transport fester Lösungen. 11 [1] Mischphasen und Chemischer Transport in den Systemen CrIII/InIII/GeIV/O,GaIII/InIII/GeIV/O,MnIII/InIII/GeIV/O und FeIII/InIII/GeIV/O

Chemical Vapor Transport of Solid Solutions. 11 Mixed Phases and Chemical Vapor Transport in the Systems Cr^III/In^III/Ge^IV/O, Ga^III/In^III/Ge^IV/O, Mn^III/In^III/Ge^IV/O und Fe^III/In^III/Ge^IV/O By means of chemical vapor transport methods the following mixed phases have been prepared: Cr_{0, 18}In_{1, 82}Ge₂O₇ (Cl₂, 950 → 850 °C), (Ga_{0, 6}In_{1, 4})₂Ge₂O₇ (Thortveitit‐type, Cl₂, 1050 → 950 °C), (Ga_{1, 9}In_{0, 1})₂Ge₂O₇ (Ga₂Ge₂O₇‐type, 1050 → 950 °C), (In_{1, 9}Mn_{0, 1})₂Ge₂O₇ (Thortveiti‐type, Cl₂, 1000 → 800 °C), mixed phase crystallizing in the Mn₂Ge₂O₇‐structure showing a composition near MnInGe₂O₇ (Cl₂, 1000 → 800 °C), Mn_{6, 5}In_{0, 5}GeO₁₂ (Braunit‐type, Cl₂, 1000 → 800 °C), (Fe_xIn_1‐x)Ge₂O₇ (Thortveitit‐type with x = 0…0, 94; Cl₂, 840 → 780 °C). Changing the compositions of the starting materials showed no effect on the composition of the deposit except for the system Fe₂O₃‐In₂O₃‐GeO₂.
