gallium    音標拼音: [g'æliəm]
n. 鎵



gallium
n 1: a rare silvery (usually trivalent) metallic element;
brittle at low temperatures but liquid above room
temperature; occurs in trace amounts in bauxite and zinc
ores [synonym: {gallium}, {Ga}, {atomic number 31}]

Gallium \Gal"li*um\, n. [NL.; perh. fr. L. Gallia France.]
(Chem.)
A rare metallic element, found combined in certain zinc ores.
It is white, hard, and malleable, resembling aluminium, and
remarkable for its low melting point (86[deg] F., 30[deg]
C.). Symbol, Ga; at. wt., 69.9. Gallium is chiefly trivalent,
resembling aluminium and indium. It was predicted with most
of its properties, under the name eka-aluminium, by the
Russian chemist Mendelyeev on the basis of the periodic law.
This prediction was verified in its discovery (in 1875) by
the French chemist Lecoq de Boisbaudran by its characteristic
spectrum (two violet lines), in an examination of a zinc
blende from the Pyrenees.
[Webster 1913 Suppl.]


Ekaluminium \Ek*al`u*min"i*um\, n. [Skr. [=e]ka one E.
aluminium.] (Chem.)
The name given by Mendeleev to a hypothetical element, --
later discovered and called {gallium}. See {Gallium}, and cf.
{Ekabor}. Also see {periodic table}.
[1913 Webster PJC]
