Indium Oxide (In2O3)
Indium oxide (also known as indium sesquioxide, or In2O3) is a yellow colored powder. It is a stable ceramic-like material that is insoluble in water. Indium oxide is an n-type semiconductor and thus can be used as a resistive element in integrated circuits. It also is used to form heterojunctions with materials like p-InP, n-GaAs, n-Si, and other semiconductors.
Other applications include glass (as a color additive), alkaline batteries (to suppress gas formation), and high current electrical switches and contacts (as an anti-arcing additive).
Indium oxide can be doped with tin dioxide to form indium tin oxide (ITO). Please see here for more information on this important transparent conductive oxide (TCO) material.
Indium Oxide is available in two powder morphologies, type A (crystalline) and type B (fine). Please refer to the product data sheet for more information on particle size specifications.
