indium    音标拼音: ['ɪndiəm]
n. 铟

铟

indium
n 1: a rare soft silvery metallic element; occurs in small
quantities in sphalerite [synonym: {indium}, {In}, {atomic
number 49}]

Indium \In"di*um\, n. [NL. See {Indigo}.] (Chem.)
A rare metallic element, of atomic number 49, discovered in
certain ores of zinc, by means of its characteristic spectrum
of two indigo blue lines; hence, its name. In appearance it
resembles zinc, being white or lead gray, soft, malleable and
easily fusible, but in its chemical relation it resembles
aluminium or gallium (valence 3). Symbol In. Atomic weight,
114.82.
[1913 Webster PJC]
