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. [47] [48] 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]
The State Department said it was planning to buy $400 million worth of armored Teslas this year. It now says it will be buying "Armored Electric Vehicles" instead of specifically Teslas.
Tin telluride is a compound of tin and tellurium (SnTe); is a IV-VI narrow band gap semiconductor and has direct band gap of 0.18 eV. It is often alloyed with lead to make lead tin telluride, which is used as an infrared detector material.
In the study, rats that ingested titanium dioxide every day showed signs of a flared-up immune systems and pre-cancerous lesions. (Don’t miss these other 8 cancer-causing foods you should stop ...
