1. Brief introduction of bismuth metal
1.1 Definition of bismuth metal, characteristics and usage
Bismuth is a metal which is silver in color. Its density is 9.8 with a melting point of about 271.3℃ and boiling point at 1560℃. Bismuth has low power and thermal conductivity.
At room temperature, bismuth does not react with oxide or water and is stable when exposed to air. When heated, it will burn, giving out a blue flame and turning into bismuth oxide. Bismuth does not dissolve in water. It will not react with concentrated sulfuric acid or hydrochloric acid unless heated; but it dissolves in concentrated nitric acid.
Bismuth is used to produce eutectic alloys with lead, tin, copper, cadmium, indium and mercury. In the metallurgical industry, bismuth can be used as an additive in the production of aluminum and steel. In medicine, bismuth can be used to produce astringents. Bismuth oxy carbonate can be used to cure intestinal conditions. The compounds of bismuth can be used in glass and superconducting materials.
