Indium Oxide

Indium oxide is faint yellow amorphous powder, which turns red brown when heating. It is insoluble in water, but soluble in hot inorganic acids. In2O3 in atmosphere of hydrogen or other reducing agents change into indium metal or other low value oxide of indium. Indium metal or indium hydroxide is the raw material.

Indium(III) oxide uses as spectral pure reagent, raw material for electronic components and so on. Nano powder In2O3 is raw material for transparent conductive coating or film. 

Indium trioxide uses as protective coating of metal reflecting surface, semiconductor film of electro-optic display. It is also raw material for indium tin oxide (ITO), glass and other indium salts as indium sulfate, indium nitride powder, indium sulfide powder, indium trichloride and so on.
