bis·muth

(bĭz′məth)

n. Symbol Bi

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. See Periodic Table.

[Obsolete German Bismuth; see kweit- in Indo-European roots.]

bis′muth•al, adj.

bis·muth

(bĭz′məth)

Symbol Bi A brittle, pinkish-white, crystalline metallic element that occurs in nature as a free metal and in various ores. Bismuth has the greatest resistance to being magnetized of all metals and has the highest atomic number of all stable elements. It is used to make low-melting alloys for fire-safety devices. Atomic number 83. See Periodic Table.
