tellurium    音标拼音: [tɛl'ʊriəm]
n. 两性金属元素,符号Te,原子序52

两性金属元素,符号Te,原子序52

tellurium
n 1: a brittle silver-white metalloid element that is related to
selenium and sulfur; it is used in alloys and as a
semiconductor; occurs mainly as tellurides in ores of
copper and nickel and silver and gold [synonym: {tellurium},
{Te}, {atomic number 52}]

Tellurium \Tel*lu"ri*um\, n. [NL., from L. tellus, -uris, the
earth.] (Chem.)
A rare nonmetallic element, analogous to sulphur and
selenium, occasionally found native as a substance of a
silver-white metallic luster, but usually combined with
metals, as with gold and silver in the mineral sylvanite,
with mercury in Coloradoite, etc. Symbol Te. Atomic weight
125.2.
[1913 Webster]

{Graphic tellurium}. (Min.) See {Sylvanite}.

{Tellurium glance} (Min.), nagyagite; -- called also {black
tellurium}.
[1913 Webster]
