Indium(III) telluride (In2 Te3) 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, similar to Silicon. 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.
