tel·lu·ri·um

 (tĕ-lo͝or′ē-əm)
n. Symbol Te
A brittle, silvery-white, rare metallic element usually found in combination with gold and other metals, produced commercially as a byproduct of the electrolytic refining of copper and used in compact discs, semiconductors, ceramics, and blasting caps and (in the form of bismuth telluride) in thermoelectric devices. In alloys it improves the machinability of stainless steel or copper, and increases the durability and hardness of lead. Atomic number 52; atomic weight 127.60; melting point 449.5°C; boiling point 988°C; specific gravity 6.23 (20°C); valence 2, 4, 6. See Periodic Table.

[From Latin tellūs, tellūr-, earth (by contrast with uranium, under a conception of the latter as an element of the heavens because of its being named after the planet Uranus).]

tellurium

(tɛˈlʊərɪəm)
n
(Elements & Compounds) a brittle silvery-white nonmetallic element occurring both uncombined and in combination with metals: used in alloys of lead and copper and as a semiconductor. Symbol: Te; atomic no: 52; atomic wt: 127.60; valency: 2, 4, or 6; relative density: 6.24; melting pt: 449.57±0.3°C; boiling pt: 988°C
[C19: New Latin, from Latin tellūs the earth, formed by analogy with uranium]

tel•lu•ri•um

(tɛˈlʊər i əm)

tel·lu·ri·um

(tĕ-lo͝or′ē-əm)
Symbol Te A nonmetallic element that occurs as either a brittle, shiny, silvery-white crystal or a gray or brown powder. Small amounts of tellurium are used to improve the alloys of various metals. Atomic number 52. See Periodic Table.
