Bismuth Carbonate is a water insoluble Bismuth source that can easily be converted to other Bismuth compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. Bismuth Carbonate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.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 is a Block P, Group 15, Period 6 element. The number of electrons in each of Bismuth's shells is 2, 8, 18, 32, 18, 5 and its electronic configuration is [Xe] 4f14 5d10 6s2 6p3. In its elemental form bismuth's CAS number is 7440-69-9. The bismuth atom has a radius of 154.5.pm and it's Van der Waals radius is 200.pm. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal, except mercury. Bismuth is not toxic. 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). Bismuth expands 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 235 U or 233 U 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 was first discovered by Early Man. The name Bismuth originates from the German word 'wissmuth' meaning white mass. See Bismuth research below.
PACKAGING SPECIFICATIONS FOR BULK & RESEARCH QUANTITIES
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Shipping documentation includes a Certificate of Analysis and Material Safety Data Sheet (MSDS). Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes.
