• Description: Bismuth is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal. It occurs naturally in the metallic state and in minerals such as bismite. The most important ores are bismuthinite or bismuth glance and bismite, and countries such as Peru, Japan, Mexico, Bolivia, and Canada are major producers of bismuth. It is found as crystals in the sulphide ores of nickel, cobalt, silver, and tin. Bismuth is mainly produced as a by-product from lead and copper smelting. It is insoluble in hot or cold water. Bismuth explodes if mixed with chloric or perchloric acid. Molten bismuth explodes and bismuth powder glows red-hot on contact with concentrated nitric acid. It is flammable in powder form. Bismuth is used in the manufacture of low melting solders and fusible alloys; as key components of thermoelectric safety appliances, such as automatic shut-offs for gas and electric water-heating systems and safety plugs in compressed gas cylinders; in the production of shot and shotguns; in pharmaceuticals; in the manufacturing of acrylonitrile; and as the starting material for synthetic fibres and rubbers. Bismuth oxychloride is sometimes used in cosmetics. Also bismuth subnitrate and bismuth subcarbonate are used in medicine. Bismuth subsalicylate is used as an anti-diarrhoeal and as a treatment of some other gastrointestinal diseases.
• Physical properties: Bismuth has unusually low toxicity for a heavy metal. Bismuth is stable to both dry and moist air at ordinary temperatures. When red hot, it reacts with water to make bismuth(III) oxide. Bismuth forms trivalent and pentavalent compounds. The trivalent compounds are more common. Many of its chemical properties are similar to those of As and Sb, although they are less toxic than derivatives of those lighter elements. At elevated temperatures, the vapors of the metal combine rapidly with oxygen, forming the yellow trioxide, Bi2O3.
• Uses: Bismuth is used to make the drugs such as Pepto-Bismol for upset stomachs and diarrheaand in medicine to treat intestinal infections. Bismuth is used in the cosmetics industry toprovide the “shine” for lipsticks, eye shadow, and other products.It is added to steel and other metals as an alloy to make the metals easier to roll, press, pullinto wires, and turn on a lathe. It is also used in the semiconductor industry and to makepermanent magnets.Bismuth is similar to antimony in that it expands from the molten liquid state to the solidstate. This property makes it an excellent material to pour into molds and can produce finedetails in whatever is being molded, such as metallic printing type and similar fine castings. Several bismuth compounds have been used medicinally. Some are used for gastrointestinal distress (Pepto-Bismol contains bismuth subsalicylate). Others are used as salves and, in rare cases, for treatment of parasites. In the past, bismuth was also used to treat syphilis and malaria. Commercially, bismuth is also used in the manufacture of permanent magnets, semiconductors, and thermoelectric materials; as a catalyst in making acrylonitrile; and as an additive to improve the machinability of steels and other metals. Bismuth is also frequently used in cosmetics, generally nail polish and lipstick.
