Abstract (en)

[origin: WO03095360A1] The invention relates to a method for producing nanostructured mixed oxide having a high electrical conductivity, e.g. indium tin oxide, as well as an oxide powder, a solid body, and the use thereof as a sputter target. The oxide is produced by continuous direct oxidation, a metal material or semiconductor material being used as a smelting electrode in an oxygen plasma. The synthesis reaction is triggered at a very high temperature, followed by a thermal state which is controlled in such a way that an error-free crystalline structure allowing high mobility of electrical charges is created.
