| bismuth | <chemistry> One of the elements; a metal of a reddish white colour, 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. 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. Bismuth glance, bismuth sulphide; bismuthinite. Bismuth ocher, a native bismuth oxide; bismite. Origin: Ger. Bismuth, wismuth: cf. F. Bismuth.
