Definition

Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a silvery-white, brittle metal that is chemically similar to arsenic and antimony. Bismuth is a poor conductor of electricity and heat.

Bismuth is found in nature as a free element, but it is more commonly found as a compound in ores such as bismuthinite and bismuth glance. Bismuth is mined in many countries, including China, Mexico, and the United States.

Bismuth has a number of uses, including:

  • Metallurgical applications: Bismuth is used as an alloying agent in lead and tin. It is also used to make fusible alloys, which are used in fire sprinkler systems and other applications where a low melting point is desired.
  • Chemical applications: Bismuth is used in a variety of chemical reactions, including the production of bismuth subsalicylate, which is used as an anti-diarrhoeal medication.
  • Medical applications: Bismuth is used in the treatment of stomach ulcers and other gastrointestinal disorders. It is also used in cosmetics and skincare products.
  • Bismuth is a relatively safe metal, but it can be toxic in high doses. It is important to handle bismuth with care and to follow the safety guidelines that are provided by the manufacturer.
