Oxide IonBismuth Oxide is a highly insoluble thermally stable Bismuth source suitable for glass, optic and ceramic applications. Bismuth oxide is found naturally as the mineral bismite and sphaerobismoite but can also be achieved as a by-product of the smelting of copper and lead ores. Bismuth oxide is the most industrially vital compound of bismuth. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic High Purity (99.999%) Bismuth Oxide(Bi2O3) Powderconductivity. Metal oxide compounds arebasic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. Bismuth Oxide is also available in pellets, pieces, powders, sputtering targets, tablets, and nanopowder (from American Elements' nanoscale production facilities). See Nanotechnology for more nanotechnology applications information. Bismuth Oxide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. See safety data and research below and pricing/lead time above. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Bismuth (Bi) atomic and molecular weight, atomic number and elemental symbol Bismuth (atomic symbol: Bi, atomic number: 83) is a Block P, Group 15, Period 6 element with an atomic radius of 208.98040(. The number of electrons in each of Bismuth's shells is 2, 8, 18, 32, 18, 5 and its electron configuration is [Xe] 4f14 5d10 6s2 6p3. Bismuth Bohr ModelThe bismuth atom has a radius of 156 pm and a Van der Waals radius of 207 pm. In its elemental form, bismuth is a silvery white brittle metal. Bismuth is the most diamagnetic of all metals and, with the exception of mercury, its thermal conductivity is lower than any other metal. Elemental Bismuth Bismuth 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). Bismuth is found in bismuthinite and bismite It is also produced as a byproduct of lead, copper, tin, molybdenum and tungsten extraction. Bismuth was first discovered by Early Man. The name Bismuth originates from the German word 'wissmuth,' meaning white mass.
