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 four forms:
- Type A (crystalline)
- Type B (fine, amorphous)
- Type T (recommended for sintered sputter target applications)
- High BET oxide (similar to Type T, but with a higher BET value)

Today's Indium Mailbag question asks about the storage of indium-contained solder paste at a temperture well below the recommended temperature of -20.
Indium Mailbag is a series of blog posts where we discuss common indium-related questions. Today we answer the question: “What is the process for reclaiming indium and how much can it get for it?”
Today we discuss the technology behind the paper: “Extreme Toughening of Soft Materials with Liquid Metal” with Dr. Navid Kazem.
