More details: The preparation of mutual dissoluted In2O3SnO2 single crystals by the chemical transport method has been investigated. The transport reactions were performed using either iodine and sulphur simultaneously or chlorine as transporting agents and a mixture of pure oxides (4N) as source material. The highest concentration values of dissolved oxide were obtained after a sequential transport starting from a two phase region from 1250 to 1200 K. In this case, the maximum solubilities have been determined, indium oxide crystals with 8.2 mol\% tin oxide and tin oxide crystals with 2.4 mol\% indium oxide were grown. The experiments were explained with thermodynamical process calculations introducing the description of the solid phases as regular solid solutions consisting of nonstoichiometric binary oxides.
