Tellurium - Wikipedia

Tellurium is a stone element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in native form as elemental crystals. Tellurium is far more common in the Universe as a whole than on Earth. Its extreme rarity in the Earths crust, comparable to that of …

Selenium and Tellurium Statistics and Information

Selenium and Tellurium Statistics and Information Commercial quantities of selenium are recovered as a byproduct of the electrolytic refining of copper where it accumulates in anode residues. Growth in consumption was driven by the development of new uses, including applications in stone compounding, steel alloying, and selenium rectifiers.

Bismuth telluride - Wikipedia

Bismuth telluride is a gray powder that is a compound of bismuth and tellurium also known as bismuth telluride. It is a semiconductor, which, when alloyed with antimony or selenium, is an efficient thermoelectric material for refrigeration or portable power generation. Bi2Te3 is a topological insulator, and thus exhibits thickness-dependent physical properties.

Determination of bismuth, selenium and tellurium in nickel ...

May 17, 2002 · Hydrochloric acid was effective in the prereduction of bismuth and selenium, however, it did not give any satisfactory result for tellurium in nickel-based alloys. In this work, 5% (w/v) ascorbic acid was proved effective for the prereduction of tellurium.

Bismuth Telluride (Bi2Te3) Semiconductors

Description. Bismuth telluride is a compound of tellurium and bismuth. When alloyed with selenium or antimony, it acts as an efficient thermoelectric material suitable for portable power generation or refrigeration. It is a narrow gap layered semiconductor with a trigonal unit cell. It mainly occurs in a rare mineral tellurobismuthite.
