Bismuth is a heavy post-transition metal and the heaviest element with a primordial isotope that is effectively stable on human timescales. Natural bismuth is almost entirely ²⁰⁹Bi, now known to be very weakly radioactive by alpha decay. It has unusually low toxicity for a heavy metal, low thermal conductivity, a low melting point, and a strong tendency to form +3 compounds. These traits make it useful where lead, cadmium, or mercury are undesirable.
It is a white, crystalline, brittle metal with a pinkish tinge. It occurs in a native state. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal, except mercury. It has a high electrical resistance, and has the highest Hall effect of any metal (i.e., greatest increase in electrical resistance when placed in a magnetic field).
The name derives from the German weisse masse for "white mass" from the colour of its oxides. The ancients did not distinguish bismuth from lead. The French chemist Claude-Francois Geoffroy showed that bismuth was distinct from lead in 1753.
Bismuth, which has been known since ancient times, was often confused with lead and tin. Bismuth was first shown to be a distinct element in 1753 by Claude Geoffroy the Younger. Bismuth does occur free in nature and in such minerals as bismuthinite (Bi2S3) and bismite (Bi2O3). The largest deposits of bismuth are found in Bolivia, although bismuth is usually obtained as a by-product of mining and refining lead, copper, tin, silver and gold.
From the German Weisse Masse, meaning white mass; later Wisuth and Bisemutum. In early times bismuth was confused with tin and lead. Claude Geoffroy the Younger showed it to be distinct from lead in 1753.
Pure bismuth is a brittle, crystalline metal with a silvery white surface that often shows a pinkish tint. Fresh crystals readily develop iridescent oxide films. It expands on solidifying, a behavior shared by few common elements.
Bismuth is used in low-melting alloys for fire-sprinkler links, fuses, solders, and precision casting. It is a common lead substitute in some free-machining metals, shot, fishing weights, and plumbing-related solders. Bismuth compounds are used in cosmetics, pigments, pharmaceuticals, and catalysts. Bismuth subsalicylate, C₇H₅BiO₄, is a long-established gastrointestinal medicine, and bismuth oxychloride, BiOCl, gives pearly effects in cosmetic formulations.
Pure bismuth is a white, brittle metal with a slight pink color. Bismuth is usually mixed with other metals, such as lead, tin, iron or cadmium to form low-melting alloys. These alloys are used in such things as automatic fire sprinkler systems, fire detection systems and electrical fuses.
Bismuth oxide (Bi2O3), a bismuth compound, is used as a yellow pigment in paints and cosmetics. Bismuth oxychloride (BiOCl) is used to make a pigment known as bismuth white. Bismuth carbonate (Bi2(CO3)3) is used to treat diarrhea and gastric ulcers.
Once thought to be the heaviest stable isotope to exist in nature, experiments conducted in 2002 showed that bismuth-209 is unstable and decays into thallium-205 through alpha decay. Bismuth-209 has a half-life of roughly 19,000,000,000,000,000,000 years.
"Bismanol" is a permanent magnet of high coercive force, made of MnBi, by the U.S. Naval Surface Weapons Center. Bismuth expands 3.32% on solidification. This property makes bismuth alloys particularly suited to the making of sharp castings of objects subject to damage by high temperatures. With other metals such as tin, cadmium, etc., bismuth forms low-melting alloys which are extensively used for safety devices in fire detection and extinguishing systems. Bismuth is used in producing malleable irons and is finding use as a catalyst for making acrylic fibers. When bismuth is heated in air it burns with a blue flame, forming yellow fumes of the oxide. The metal is also used as a thermocoupling material, and has found application as a carrier for 235U or 233U fuel in nuclear reactors. Its soluble salts are characterized by forming unsoluble basic salts on the addition of water, a property sometimes used in detection work. Bismuth oxychloride is used extensively in cosmetics. Bismuth subnitrate and subcarbonate are used in medicine.
Isotopes in Medicine
212Bi and 213Bi (with half-lives of 1 h and 0.76 h, respectively) are both used in medicine for radioimmunotherapy as bismuth-labeled monoclonal antibodies to treat cancer cells from melanoma (skin cancer) (Fig. IUPAC.83.1) and ovarian cancer [559] D. E. Milenic, M. Roselli, S. Mirzadeh, C. G. Pippin, O. A. Gansow, D. Colcher, M. W. Brechbiel, J. Schlom. Cancer Biother. Radiopharm.16, 133 (2001).. Figure 4.83.2 compares the biologic effect of 131I and 213Bi using a specific monoclonal antibody, B-B4, coupled to 213Bi by a chelating agent (a substance that can form multiple bonds to a single metal ion). 213Bi is a mixed alpha and beta emitter with a half-life of 0.76 h. The primary mode of decay is by beta emission to the very short-lived alpha emitter 213Po. The 8.4 MeV alpha particle emitted by 213Po has a path length of 76 μm in human tissue and is responsible for its cytotoxic effects (toxic to living cells). 213Bi is produced from a series of alpha particle decays beginning with 225Ac, which is a pure alpha emitter with a half-life of 10 days. A schematic of the Institute for Transuranium Elements (ITU) Standard 225Ac/ 213Bi Radionuclide Generator is shown in Fig. IUPAC.83.3.
212Bi has been used for radioimmunotherapy of leukemia and for targeting the vascular endothelial cells (thin layer of simple squamous cells that forms the interface between circulating blood or lymph and the remainder of the vessel wall) of tumors [560] F. Hartmann, E. M. Horak, K. Garmestani, C. Wu, M. W. Brechbiel, R. W. Kozak, J. Tso, S. A. Kosteiny, O. A. Gansow, D. L. Nelson. Cancer Res.54, 4362 (1994)..
Isotopes Used as a Source of Radioactive Isotope(s)
209Bi is bombarded with neutrons in a nuclear reactor to form radioactive 210Bi. The 210Bi (with a half-life of 5 days) decays via the reaction 210Bi→ 210Po+β −. The half-life of 210Po is 138 days and it is used in static eliminators in machinery [75] J. Peterson, M. McDonell, L. Haroun, F. Monette, R. D. Hildebrand, A. Taboas.

Bismuth chemistry is dominated by the +3 oxidation state, with the +5 state less stable and strongly oxidizing in many compounds. Bismuth(III) oxide, Bi₂O₃, is an important oxide with several polymorphs and high oxide-ion conductivity in some phases. Bismuth trichloride, BiCl₃, hydrolyzes readily in water to give oxychloride species. Bismuth nitrate pentahydrate, Bi(NO₃)₃·5H₂O, is a common laboratory precursor. Organobismuth compounds exist but are less broadly used than analogous phosphorus or arsenic chemistry.
See more information at the Bismuth compound page.
Elemental bismuth and many insoluble bismuth compounds are comparatively low in toxicity, but this does not make all bismuth materials harmless. Soluble salts, dusts, and pharmaceutical overuse can cause adverse effects, including kidney or neurological problems in severe cases. Molten bismuth presents ordinary burn and metal-fume precautions. Natural ²⁰⁹Bi is radioactive only at an extremely low specific activity, so its radiological hazard is normally negligible.
Bismuth occurs at low abundance in the crust, commonly associated with sulfide ores of lead, copper, tin, and tungsten. Native bismuth and minerals such as bismuthinite, Bi₂S₃, are known but not usually mined alone. In soils and waters, bismuth tends to form sparingly soluble oxides, sulfides, and basic salts, limiting mobility under many conditions. It has no established essential biological role.
Bismuth is obtained mainly as a by-product of refining lead, copper, tin, tungsten, and other metal ores, rather than from dedicated bismuth mines. Supply therefore depends strongly on the processing of other metals. Demand is supported by substitution for more toxic heavy metals, especially lead, and by uses in alloys, chemicals, and pharmaceuticals. Recycling occurs from some alloy and manufacturing scrap, but dispersed uses in cosmetics, medicines, and small components are difficult to recover economically.
The most important ores are bismuthinite or bismuth glance and bismite. Peru, Japan, Mexico, Bolivia, and Canada are major bismuth producers. Much of the bismuth produced in the U.S. is obtained as a by-product in refining lead, copper, tin, silver, and gold ores.
Bismuth is a rare heavy element in cosmic terms. Its stable primordial inventory was made mainly by neutron-capture processes in earlier generations of stars, with contributions from the slow and rapid neutron-capture pathways. In planetary materials it behaves as a chalcophile and siderophile trace element, concentrating preferentially in sulfide-rich and metallic phases rather than in common silicates.
- Bismuth is more strongly diamagnetic than any other stable metal.
- Its liquid form is denser than its solid form, so it expands when it freezes.
- The half-life of ²⁰⁹Bi is about 1.9 × 10¹⁹ years.
- Bismuth crystals sold as ornaments usually owe their colors to a thin oxide film.
- Bismuth telluride, Bi₂Te₃, is a major thermoelectric material near room temperature.
