antimony    
n. 锑

锑

antimony
n 1: a metallic element having four allotropic forms; used in a
wide variety of alloys; found in stibnite [synonym: {antimony},
{Sb}, {atomic number 51}]

Antimony \An"ti*mo*ny\ ([a^]n"t[i^]*m[-o]*n[y^]; 112), n. [LL.
antimonium, of unknown origin.] (Chem.)
An elementary substance, resembling a metal in its appearance
and physical properties, but in its chemical relations
belonging to the class of nonmetallic substances. Atomic
weight, 120. Symbol, Sb.
[1913 Webster]

Note: It is of tin-white color, brittle, laminated or
crystalline, fusible, and vaporizable at a rather low
temperature. It is used in some metallic alloys, as
type metal and bell metal, and also for medical
preparations, which are in general emetics or
cathartics. By ancient writers, and some moderns, the
term is applied to native gray ore of antimony, or
stibnite (the stibium of the Romans, and the sti`mmi of
the Greeks, a sulphide of antimony, from which most of
the antimony of commerce is obtained. Cervantite,
senarmontite, and valentinite are native oxides of
antimony.
[1913 Webster]

antimony
Symbol: Sb
Atomic number: 51
Atomic weight: 121.75
Element of group 15. Multiple allotropic forms. The stable form of
antimony is a blue-white metal. Yellow and black antimony are unstable
non-metals. Used in flame-proofing, paints, ceramics, enamels, and
rubber.
Attacked by oxidizing acids and halogens. First reported by Tholden in
1450.
