Technical characteristics

Bismuth was discovered at the beginning of the 16th century. Its name comes from the German "white mass" because this metal has a silvery-white color. The melting point is 271.4°C, the boiling point is 1564°C, and the density is 9790 ^kg/m3. It is a brittle non-toxic metal and is usually used in alloys with other metals.

Mining

This metal is mined from common ores such as bismuthinite and bismite. The main commercial source of bismuth is a byproduct of lead, copper, tin, silver and gold ore processing. Buy bismuth today is offered by Evek GmbH. The price from the manufacturer. The supplier provides prompt delivery of products to any address.

Applications of

Alloys of bismuth with tin or cadmium have low melting points and are used in fire detectors and fire extinguishers, electrical fuses and solders. BiO oxide is used as a yellow pigment for cosmetics and paints, while trivalent BiClO adds a pearlescent hue to cosmetics. Bismuth is used in the production of low-melting solders and fusible alloys, and some of its compounds are used as pharmaceuticals. Industry uses bismuth compounds as catalysts in the production of acrylonitrile, which is the starting material for synthetic fibers and rubbers. Bismuth is sometimes used in the manufacture of hunting weapons.
