Corundum-type indium (III) oxide: formation under ambient conditions in Fe2O3–In2O3 system

The influence of the iron doping on the structural transformations in In2O3 has been studied. The samples were prepared by the sol–gel technique via coprecipitation from the solution of In(III) and Fe(II) salts. For the first time, the formation of corundum-type In2O3 under ambient conditions in iron-doped In2O3 samples was observed.
