Bismuth (Bi)

White crystalline metal with a pink tinge, belongs to group 15. Most diamagnetic of all metals and has the lowest thermal conductivity of all the elements except mercury. Lead-free bismuth compounds are used in cosmetics and medical procedures. Burns in the air and produces a blue flame. In 1753, C.G. Junine first demonstrated that it was different from lead.

History

Bismuth has been known since ancient times, so no one person is credited with its discovery. The element was confused in early times with tin and lead because of its resemblance to those elements. In 1753, French chemist Claude François Geoffroy demonstrated that this metal is distinct from lead and tin. From the German Weisse Masse, meaning white mass

Uses

Bismuth is used in producing malleable irons and is used as a catalyst for making acrylic fibers. Bismuth oxychloride is used in cosmetics, as a pigment in paint for eye shadows, hair sprays and nail polishes. It has also been used as a replacement for lead in shot, bullets and less-lethal riot gun ammunition. Main use is in pharmaceuticals and low melting point alloys used as fuses.

Sources

It can be found free in nature and in minerals like bismuthine (Bi2O3) and in bismuth ochre (Bi2O3)
