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 three forms:
- Type A (crystalline)
- Type B (fine, amorphous)
- Type T (recommended for sintered sputter target applications)

I’ve always been a strong believer that a customer should not get a solder alloy that just “works” for their application, they should get the best alloy for their application. Of course, this is a compromise between all the factors that are important. Bond strength, unique properties,…
Here at Indium Corporation we produce many forms of solder. With products like solder ingots, solder paste, and solder wire - we supply the alloys our customers need in the forms they want. One form of solder that is very interesting to me is the solder preform. In this series we will explore the solder…
The Indium Corporation recently had a customer contact us looking for 50In50Pb solder wire. We manufacture large amounts of this indium-lead material as it is used in numerous applications. In this case, it was the application that was quite interesting. I won’t give any customer…
