Indium(III) telluride (In₂Te₃) is an inorganic compound. A black solid, it is sometimes described as an intermetallic compound, because it has properties that are metal-like and salt like. It is a semiconductor that has attracted occasional interest for its thermoelectric and photovoltaic applications. No applications have been implemented commercially however.^[2]

Preparation and reactions

A conventional route entails heating the elements in a seal-tube:^[3]

3Te + 2 In → In₂Te₃

Indium(III) telluride reacts with strong acids to produce hydrogen telluride.
