Elemental tellurium is used as an additive to copper, iron, and steel, in vulcanising rubber, as a colouring agent in glass and ceramics, and in some other applications (ACG99, Bud96). Certain telluride alloys are employed in the semiconductor industry (ACG99). Tellurium tetrachloride is used as a catalyst in several condensation reactions. Tellurium dioxide is used in acousto-optical filters in astronomy and in lasers, as a catalyst in oxidation reactions, in electroconductivity devices, as an additive in glass, in optical and photoacoustic devices. Tellurium trioxide is used as a catalyst in oxidation reactions (12th Collective Index of Chemical Abstracts: 12CI).
