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.
The USD to CAD exchange rate averaged 1.129 in July 2009 according to OANDA Historical Exchange Rates. Although the exact moment that the $1,075 figure [ clarification needed ] was determined is unknown, it may be considered a reasonable value for the time.
It can be synthesized by reacting elemental copper and tellurium with a molar ratio of 2:1 at 1200 °C in a vacuum. [3] Cu 2 Te has potential applications in thermoelectric elements and in solar cells , where it is alloyed with cadmium telluride to create a heterojunction .
