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)

At this point in our process we have a produced the exact alloy that you have requested. But, a large piece of solder isn’t going to help you assemble microelectronics components. We need to start manipulating the solder into a usable form; in this case a preform. NEXT STEP: The freshly-alloyed…
When it comes to manufacturing solder preforms, alloying solder is an important first step in providing consistent final parts. This is the step where the bulk physical properties are, more or less, set. Strict attention to the percentage of each element (including impurities and dopants) helps provide…
If you haven’t heard about Bi-containing (bismuth) solder alloys recently, that may change in the near future. Low-melting Bi-containing solders are now in increasing use and gaining popularity due to their lower melting temperatures—58Bi/42Sn is eutectic at 138°C and 57Bi/42Sn/1Ag melts…
