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. [48] [49] 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.

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.
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 ...
Sodium tellurite is an inorganic tellurium compound with formula Na 2 TeO 3. It is a water-soluble white solid and a weak reducing agent. Sodium tellurite is an intermediate in the extraction of the element, tellurium; it is a product obtained from anode slimes and is a precursor to tellurium.

Butternut squash is a rich source of vitamin A, an important fat-soluble vitamin that supports eye and immune health. Plus, the soup provides a good source of fiber, with 4 grams per cup.
The telluride ion is the anion Te 2− and its derivatives. It is analogous to the other chalcogenide anions, the lighter O 2−, S 2−, and Se 2−, and the heavier Po 2−. [1]In principle, Te 2− is formed by the two-e − reduction of tellurium.
