Description

General description

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.
