Bismuth is a chemical element with the symbol Bi and atomic number 83. The free element is 86% as dense as lead. It is a brittle metal with a silvery-white color when freshly produced, but surface oxidation can give it an iridescent tinge in numerous colours.
Bismuth is a white, brittle metal with a slight pink color and is typically recovered as a by-product of lead and copper. It is commonly used as an alloying element for various low melting alloys where it is mixed with other metals such as Lead, Tin, or Cadmium. The powder has a purity of 99%. ...
Bismuth is the most naturally diamagnetic element and has one of the lowest values of thermal conductivity among metals.
Bismuth has few commercial applications, and those applications that use it generally require small quantities relative to other raw materials. In the United States, for example, 733 tonnes of bismuth were consumed in 2016, of which 70% went into chemicals (including pharmaceuticals, pigments, and cosmetics) and 11% into bismuth alloys.
The Chemical Abstracts Service (CAS) number for bismuth metal are used within the recommended ranges of dosage and length of treatment.
