barium    音標拼音: [b'ɛriəm]
n. 鋇



barium
n 1: a soft silvery metallic element of the alkali earth group;
found in barite [synonym: {barium}, {Ba}, {atomic number 56}]

Barium \Ba"ri*um\, n. [NL., fr. Gr. bary`s heavy.] (Chem.)
One of the elements, belonging to the alkaline earth group; a
metal having a silver-white color, and melting at a very high
temperature. It is difficult to obtain the pure metal, from
the facility with which it becomes oxidized in the air.
Atomic weight, 137. Symbol, Ba. Its oxide called baryta.
[Rarely written {barytum}.]
[1913 Webster]

Note: Some of the compounds of this element are remarkable
for their high specific gravity, as the sulphate,
called heavy spar, and the like. The oxide was called
barote, by Guyton de Morveau, which name was changed by
Lavoisier to baryta, whence the name of the metal.
[1913 Webster]
