Tellurium dioxide is formed by heating tellurium in air, where it burns with a blue flame. [2] Tellurium trioxide, β-TeO 3, is obtained by thermal decomposition of Te(OH) 6. The other two forms of trioxide reported in the literature, the α- and γ- forms, were found not to be true oxides of tellurium in the +6 oxidation state, but a mixture ...
The telluride oxides or oxytellurides are double salts that contain both telluride and oxide anions (Te 2− and O 2−).They are in the class of mixed anion compounds.. Compounds that can be mistakenly called "telluride oxides" are tellurium dioxide and tellurite.

Tellurite is a oxyanion of tellurium with the formula TeO 2− 3. It is the ion of tellurous acid, and is chemically related to tellurium dioxide (TeO 2), whose mineral appearance also bears the name tellurite. Tellurites are typically colorless or white salts, which in some ways are comparable to sulfite. [3]
