Tellurium dioxide (TeO 2) is a solid oxide of tellurium. It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO 2, and the synthetic, colourless tetragonal (paratellurite), α-TeO 2. [2] Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite, α-TeO 2. [3]
3 in vacuum, disproportionating into tellurium dioxide, TeO 2 and elemental tellurium upon heating. [7] [8] Since then, however, existence in the solid phase is doubted and in dispute, although it is known as a vapor fragment; the black solid may be merely an equimolar mixture of elemental tellurium and tellurium dioxide.

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]
Tellurite is a rare oxide mineral composed of tellurium dioxide (Te O 2).. It occurs as prismatic to acicular transparent yellow to white orthorhombic crystals. It occurs in the oxidation zone of mineral deposits in association with native tellurium, emmonsite and other tellurium minerals.
Tellurium oxide may refer to: Tellurium monoxide, TeO; Tellurium dioxide, TeO 2; Tellurium trioxide, TeO 3 This page was last edited on 13 May 2022 ...
Tellurous acid is an inorganic compound with the formula H 2 TeO 3. It is the oxoacid of tellurium(IV). [2] This compound is not well characterized. An alternative way of writing its formula is (HO) 2 TeO. In principle, tellurous acid would form by treatment of tellurium dioxide with water, that is by hydrolysis.
