Indium(III) oxide

Indium(III) oxide (In₂O₃) is a chemical compound, an amphoteric oxide of indium.

ndium oxide is used in some types of batteries, thin film infrared reflectors transparent for visible light (hot mirrors), some optical coatings, and some antistatic coatings. In combination with tin dioxide, indium oxide forms indium tin oxide (also called tin doped indium oxide or ITO), a material used for transparent conductive coatings.

In semiconductors, indium oxide can be used as an n-type semiconductor used as a resistive element in integrated circuits.

In histology, indium oxide is used as a part of some stain formulations.
