Typical and ongoing research includes Bi 2 Te 3, and La 3-x Te 4, etc. Bi 2 Te 3 is widely used from energy conversion to sensing to cooling due to its great TE properties. The BiTe-based TE material can achieve a conversion efficiency of 8%, an average zT value of 1.05 for p-type and 0.84 for n-type bismuth telluride alloys. [ 81 ]
Minerals containing the chemical element tellurium Note (New Dana Classification): Telluride minerals are in the category: Sulfides and Sulfosalts (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.) too

Tellurium compounds are compounds containing the element tellurium (Te). Tellurium belongs to the chalcogen (group 16) family of elements on the periodic table, which also includes oxygen, sulfur, selenium and polonium: Tellurium and selenium compounds are similar. Tellurium exhibits the oxidation states −2, +2, +4 and +6, with +4 being most ...
There are 39 known isotopes and 17 nuclear isomers of tellurium (52 Te), with atomic masses that range from 104 to 142. These are listed in the table below. Naturally-occurring tellurium on Earth consists of eight isotopes. Two of these have been found to be radioactive: 128 Te and 130 Te undergo double beta decay with half-lives of, respectively, 2.2×10 24 (2.2 septillion) years (the longest ...
A tellurion (also spelled tellurian, tellurium, and yet another name is loxocosm), is a clock, typically of French or Swiss origin, surmounted by a mechanism that depicts how day, night, and the seasons are caused by the rotation and orientation of Earth on its axis and its orbit around the Sun.
Tellurium compounds are chemical compounds of the chemical element tellurium.. Note (New Dana Classification): Telluride minerals are in the category: Sulfides and Sulfosalts (sulfides, selenides, tellurides; arsenides, antimonides, bismuthides; sulfarsenites, sulfantimonites, sulfbismuthites, etc.) too
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.
