Bismuth

About Bismuth (Bi)

Symbol: Bi
Atomic number: 83
Atomic mass: 208.9804
Element category: Post-transition metal

Bismuth (Symbol: Bi, atomic number: 83) is a white, crystalline and brittle metal. It exhibits a silver appearance when freshly produced and, on exposure to air, its surface develops a pinkish tint. It is the most strongly diamagnetic element and shows a lower thermal conductivity than any metal with the exception of mercury.

Bismuth compounds are employed in semiconductor devices, electronic cooling components, thermoelectric conversion systems and as a liquid coolant in nuclear reactors. Bismuth is alloyed with tin or cadmium because of its natural brittleness. These low-melting alloys are utilised in fire detectors, fire extinguishers, electrical fuses and soldering materials.

Bismuth oxide is used as a yellow pigment in cosmetics and paints, whereas bismuth(III)-chloridoxid (BiClO) is incorporated in cosmetics to create a pearlescent effect. Basic bismuth carbonate is formulated in tablet or liquid form and is applied to treat digestive disorders as a “bismuth mixture”.

Popular Bismuth Products: Bismuth Metal, Bismuth Trioxide (Bi2O3), Bismuth Sulfide (Bi2S3), Bismuth Selenide (Bi2Se3)

Applications of Bismuth

Bismuth and its compounds are utilised in a variety of industries on the basis of defined physical properties. In the medical field, bismuth is incorporated in medications for gastrointestinal disorders. It produces a measurable soothing effect on the stomach lining and demonstrates lower toxicity relative to other heavy metals.

In cosmetics, bismuth is employed in powders and creams to achieve a pearlescent finish. Bismuth is alloyed with other metals when a low melting point is essential for applications such as soldering and plumbing. In electronics, bismuth’s thermoelectric properties are utilised in semiconductor materials and electronic cooling components. Bismuth compounds also function as a liquid coolant in nuclear reactors.
