    en.wikipedia.org/wiki/Prices_of_chemical_elements

    This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.

  3. Tellurium - Wikipedia

    en.wikipedia.org/wiki/Tellurium

    The year-end price for tellurium in 2000 was US$30 per kilogram. In recent years, the tellurium price was driven up by increased demand and limited supply, reaching as high as US$220 per pound in 2006. [38] [39] The average annual price for 99.99%-pure tellurium increased from $38 per kilogram in 2017 to $74 per kilogram in 2018. [34]

  4. Cadmium telluride - Wikipedia

    en.wikipedia.org/wiki/Cadmium_telluride

    At the present time, the prices of the raw materials cadmium and tellurium are a negligible proportion of the cost of CdTe solar cells and other CdTe devices. However, tellurium is a relatively rare element (1–5 parts per billion in the Earth's crust; see Abundances of the elements (data page)).

  5. Tellurium compounds - Wikipedia

    en.wikipedia.org/wiki/Tellurium_compounds

    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 ...

  6. Gallium(II) telluride - Wikipedia

    en.wikipedia.org/wiki/Gallium(II)_telluride

    GaTe produced from the elements has a monoclinic crystal structure. Each gallium atom is tetrahedrally coordinated by 3 tellurium and one gallium atom. The gallium-gallium bond length in the Ga 2 unit is 2.43 Angstrom. The structure consists of layers and can be formulated as Ga 2 4+ 2Te 2−. [2]

  7. Mercury cadmium telluride - Wikipedia

    en.wikipedia.org/wiki/Mercury_cadmium_telluride

    Hg 1−x Cd x Te or mercury cadmium telluride (also cadmium mercury telluride, MCT, MerCad Telluride, MerCadTel, MerCaT or CMT) is a chemical compound of cadmium telluride (CdTe) and mercury telluride (HgTe) with a tunable bandgap spanning the shortwave infrared to the very long wave infrared regions.

    en.wikipedia.org/wiki/Tellurium_Copper

    ASTM specification B301 has 0.5% tellurium; at concentrations of up to 0.75% machinability is improved while electrical conductivity and hot working behavior is maintained. Mechanical properties are similar to tough pitch copper , while machinability is similar to brass - the hardness of the alloy is increased by precipitation of the copper ...
