Indium Corp. has released IndiOx™ (In2O3) for use in the manufacture of ITO sputtering targets for thin-film coating. IndiOx™ (In2O3) is a stable ceramic-like material that is insoluble in water and volatizes at 850°C.
When doped with tin oxide, IndiOx™ forms ITO, the material of choice to form transparent conductive oxide (TCO) layers in flat-panel displays and touch sensors for mobile devices. The ITO layer is deposited onto glass from a sputtering target that is manufactured from the ITO powder by sintering.
Other uses for IndiOx™ include glass coloring, gassing suppression in alkaline batteries, and as an anti-arcing additive in high current electrical switches and contactors.
IndiOx™ is available in three powder types:
- Type A – Crystalline: particle size distribution D10–D90 ranges from 0.8 to 38 μm.
- Type B – Fine: particle size distribution D10–D90 ranges from 0.5 to 6 μm.
- Type T – Target Grade: particle size distribution D10–D90 ranges from 0.1 to 7.5 μm. The primary particle size is about 100 nm.
