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.
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]
Lead telluride is a compound of lead and tellurium (PbTe). It crystallizes in the NaCl crystal structure with Pb atoms occupying the cation and Te forming the anionic lattice. It is a narrow gap semiconductor with a band gap of 0.32 eV. [4] It occurs naturally as the mineral altaite.
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)).

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]
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 ...
