Indium(III)oxide, also known as indium sesquioxide or In2O3. It is athermally stable compound, suitable for use in glass, optic, and ceramic applications.Indium oxide is also commonly doped with tin oxide (SnO2) to produce indium tinoxide (ITO), which is used in transparent thin conductive films for displays,energy-efficient windows, and photovoltaics. Indium oxide-based catalysts are alsoused in various catalytic applications including CO2 hydrogenation, directconversion of syngas into light olefins, and conversion of meso-epoxide intochiral β-amino alcohols.
