Definition of 'Bismuth'

From: 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. [1913 Webster]

  • 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.
