  • noun A brittle, crystalline, highly diamagnetic metallic element with a very low thermal conductivity and a pinkish-white luster, used in alloys to form sharp castings for objects sensitive to high temperatures and in various low-melting alloys for fire-safety devices. Atomic number 83; atomic weight 208.98; melting point 271.3°C; boiling point 1,564°C; specific gravity 9.78; valence 3, 5. cross-reference: Periodic Table.

  • noun (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° 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.
  • noun bismuth sulphide; bismuthinite.
  • noun a native bismuth oxide; bismite.
