Image copyright: smart-elements.com A silvery-white, metalloid element in group VIA of the periodic table, occurring as heavy-metal tellurides, and extracted as a by-product of copper refining. Tellurium resembles selenium in its chemistry, but is rather more metallic; tellurium (IV) compounds resemble platinum (IV). It is added to metals to make them easier to machine and to lead for greater corrosion resistance; bismuth telluride is used in thermoelectric devices. atomic number 52 relative atomic mass 127.6 relative density 6.24 melting point 450°C (842°F) boiling point 1,390°C (2,534°F) Related category    • INORGANIC CHEMISTRY Also on this site: Encyclopedia of Alternative Energy & Sustainable Living Encyclopedia of History Transport Concepts & Designs (partner site) BACK TO TOP
