Indium(III) telluride (In2Te3) is a 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
editA 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.
