Bismuth
(gcide) | Bismuth \Bis"muth\, n. [Ger. bismuth, wismuth: cf. F. bismuth.]
(Chem.)
One of the elements; a metal of a reddish white color,
crystallizing in rhombohedrons. It is somewhat harder than
lead, and rather brittle; masses show broad cleavage surfaces
when broken across. It melts at 507[deg] Fahr., being easily
fused in the flame of a candle. It is found in a native
state, and as a constituent of some minerals. Specific
gravity 9.8. Atomic weight 207.5. Symbol Bi.
[1913 Webster]
Note: Chemically, bismuth (with arsenic and antimony is
intermediate between the metals and nonmetals; it is
used in thermo-electric piles, and as an alloy with
lead and tin in the fusible alloy or metal. Bismuth is
the most diamagnetic substance known.
[1913 Webster]
Bismuth glance, bismuth sulphide; bismuthinite.
Bismuth ocher, a native bismuth oxide; bismite.

bismuth
(wn) | bismuth
n 1: a heavy brittle diamagnetic trivalent metallic element
(resembles arsenic and antimony chemically); usually
recovered as a by-product from ores of other metals [syn:
bismuth, Bi, atomic number 83] |
bismuthal
(wn) | bismuthal
adj 1: of or relating to bismuth |
bismuthic
(wn) | bismuthic
adj 1: containing bismuth (especially in the pentavalent state) |
bismuth
(elements) | bismuth
Symbol: Bi
Atomic number: 83
Atomic weight: 208.980
White crystalline metal with a pink tinge, belongs to group 15. Most
diamagnetic of all metals and has the lowest thermal conductivity of all
the elements except mercury. Lead-free bismuth compounds are used in
cosmetics and medical procedures. Burns in the air and produces a blue
flame. In 1753, C.G. Junine first demonstrated that it was different
from
lead.
