Kev lag luam siv bismuth

Bismuth is mainly used in the manufacture of fusible alloys, with a melting point ranging from 47 to 262 °C. The most commonly used alloys of bismuth with metals such as lead, tin, antimony, and indium are used in fire-fighting devices, automatic sprinklers, and safety plugs for boilers. , in the event of a fire, the pistons of some water pipes will "automatically" melt and spray water. In the fire protection and electrical industries, it is used for automatic fire extinguishing systems and electrical fuses and solders. Bismuth alloys have the property of not shrinking when solidified, and are used for casting and printing type and high-precision molds. Bismuth oxycarbonate and bismuth oxynitrate are used to treat skin lesions and gastrointestinal disorders.

Nws yog siv los ua cov alloys uas tsis tshua muaj melting thiab muaj qhov tseem ceeb tshwj xeeb hauv kev tiv thaiv hluav taws thiab cov khoom siv hluav taws xob kev nyab xeeb.

Hauv analytical chemistry rau kev kuaj pom ntawm Mn. Bismuth tuaj yeem siv los ua cov hlau nplaum uas tsis tshua muaj melting point, uas yog siv rau hauv cov khoom siv kaw tsis siv neeg lossis cov khoom txav tau yooj yim.
