tellurium dioxide tetrachloride

Polonium tetrachloride - Wikipedia

Polonium tetrachloride (also known as polonium(IV) chloride) is a chemical compound with the formula Po Cl 4.It is a hygroscopic bright yellow crystalline solid at room temperature. Above 200 °C, it tends to decompose into polonium dichloride and excess chlorine, similar to selenium tetrachloride and tellurium tetrachloride.

Tellurium Oxide - espimetals.com

To the best of our knowledge the chemical, physical and toxicological properties of tellurium oxide have not been thoroughly investigated and recorded. Elemental tellurium has relatively low toxicity. It is converted in the body to dimethyl telluride which imparts a garlic-like odor to the breath and sweat.

Tellurium Dioxide, TeO2

Tellurium dioxide possesses definite basic tendencies, the tellurium being capable of acting as a quadrivalent atom and the group TeO, telluryl, as a bivalent basic radical. When heated in a current of dry hydrogen chloride or with solid ammonium chloride, tellurium dioxide forms the tetrachloride.

Tellurium tetrafluoride - Wikipedia

Tellurium tetrafluoride can be prepared by the following reaction: TeO 2 + 2SF 4 → TeF 4 + 2SOF 2. It is also prepared by reacting nitryl fluoride with tellurium or from the elements at 0 °C or by reacting selenium tetrafluoride with tellurium dioxide at 80 °C. Fluorine in nitrogen can react with TeCl 2 or TeBr 2 …

Tellurium tetrafluoride - Wikipedia

Tellurium tetrafluoride, TeF 4, is a stable, white, hygroscopic crystalline solid and is one of two fluorides of tellurium.The other binary fluoride is tellurium hexafluoride. The widely reported Te 2 F 10 has been shown to be F 5 TeOTeF 5 There are other tellurium compounds that contain fluorine, but only the two mentioned contain solely tellurium and fluorine.
