Material Notes:
Indium Sesquioxide is a yellow colored powder. It is a stable ceramic-like material, insoluble in water and volatizes at 850°C. Indium sesquioxide is a n-type semiconductor and as such is used as a resistive element in integrated circuits and to form heterojunctions with p-InP, n-GaAs and other semiconductors. Other uses include glass coloring, in alkaline batteries to suppress gassing and as an anti-arcing additive in high current electrical switches and contactors.When doped with tin dioxide, thin films of indium-tin oxide (ITO) function as a transparent electrical conductor and can reflect a portion of the infrared spectrum. The major use of indium oxide is in the manufacture of ITO sputtering targets for thin film coating.Type A - Crystalline: The primary particles range from 0.4 to 1.0 microns in diameter; agglomerates up to approximately 30 microns.PropertiesChemical Formula: In2O3General Description: Bright yellow powderPurity Grades Available: 4N (99.99%), 5N (99.999%)Solubility: Insoluble in water and alcohol.UsesManufacturing of ITO sputtering targets and evaporation chargesColoring ceramics and glassesInformation provided by the manufacturer, Indium Corporation of America.
