Reaction with ammonia forms a heat-sensitive explosive product. When heated to decomposition it emits toxic fumes of Br⁻ and Te. See also TELLURIUM COMPOUNDS and BROMIDES.

  Tellurium tetrabromide with CAS registry number of 10031-27-3 is an inorganic chemical compound, also known as Tellurium bromide (TeBr₄), (T-4)- . It is yellow-orange crystals with a similar tetrameric structure to TeCl₄ . It can be made by reaction of  bromine with tellurium . Tellurium tetrabromide is a conductor when molten, dissociating into the ions TeBr³⁺ and Br^- . Solutions in benzene and toluene are non conducting and the product is present as the tetramer. However, in solvents with donor properties, complexes are formed which can make the solution conducting.
