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.
