Chemical vapor transport of solid solutions. 9. The chemical vapor transport of solid solutions in the system iron(II)/(cobalt(II)and manganese(II)/cobalt(II) germanate [German]

摘要

By means of chemical vapor transport methods (900 --> 700degreesC) using HCl as transport agent FeGeO3, Fe2GeO4 and MnGeO3 have been prepared. Co2GeO4 and Fe2GeO4 as well as CoGeO3 and FeGeO3 form continuous crystalline solid solutions, whereas in MnO/CoO/GeO2 two different phases (MnxCo1-x)GeO3 are formed. All of these systems Show Congruent transport behaviour. Chemical vapor transport has been proved a suitable method to prepare solid solutions. [References: 12]
