Characteristics of High purity Bismuth

Bismuth is a actinic aspect with attribute Bi and diminutive amount 83. Bismuth, a trivalent poor metal, chemically resembles arsenic and antimony. Elemental bismuth may action by itself uncombined, although its sulfide and oxide anatomy important bartering ores. The chargeless aspect is 86% as close as lead. It is a breakable metal with a ablaze white blush if afresh produced, but is generally credible in air with a blush cast attributable to credible oxidation. Bismuth metal has been accepted from age-old times, although until the 18th century, it was generally abashed with advance and tin, which anniversary accept some of the metal's aggregate concrete properties. The ancestry is uncertain, but possibly comes from Arabic bi ismid, acceptation accepting the backdrop of antimony or German words weisse masse or wismuth acceptation "white mass".
Bismuth is the a lot of by itself diamagnetic of all metals, and alone mercury has a lower thermal conductivity.
Bismuth has classically been advised to be the heaviest by itself occurring abiding element, in agreement of diminutive mass. Recently, however, it has been begin to be actual hardly radioactive: its alone basic isotope bismuth-209 decays via alpha adulteration into thallium-205 with a half-life of added than a billion times the estimated age of the universe.
Bismuth compounds (accounting for about bisected the assembly of bismuth) are acclimated in cosmetics, pigments, and a few pharmaceuticals, conspicuously Pepto-Bismol. Bismuth has almighty low toxicity for a abundant metal. As the toxicity of advance has become added credible in contempo years, admixture uses for bismuth metal (presently about a third of bismuth production), as a backup for lead, accept become an accretion allotment of bismuth's bartering importance.
Characteristics:
Bismuth is a brittle metal with a white, silver-pink hue, often occurring in its native form with an iridescent oxide tarnish showing many refractive colors from yellow to blue.
