High purity Bismuth 99.9999%
5n-6n, 99.999%
Bismuth is a silvery, crystalline, brittle metal when freshly produced and it often presents a pinkish tinge in the air. Bismuth is the most diamagnetic element, and its thermal conductivity is lower than any metal except mercury. It has a high electrical resistance and the highest Hall coefficient.
Purity: 99.9999%（6N）
Bismuth is the most naturally diamagnetic element, and has one of the lowest values of thermal conductivity among metals.
Bismuth compounds account for about half the production of bismuth. They are used in cosmetics, pigments, and a few pharmaceuticals, notably bismuth subsalicylate, used to treat diarrhea.
The most important sustainability fact about bismuth is its byproduct status, which can either improve sustainability (i.e., vanadium or manganese nodules) or, for bismuth from lead ore, constrain it; bismuth is constrained. The extent that the constraint on bismuth can be ameliorated or not is going to be tested by the future of the lead storage battery, since 90% of the world market for lead is in storage batteries for gasoline or diesel-powered motor vehicles.
Bismuth is used in metal alloys with other metals such as iron, to create alloys to go into automatic sprinkler systems for fires. Also used to make bismuth bronze which was used in the Bronze Age.
Bismuth, as a dense element of high atomic weight, is used in bismuth-impregnated latex shields to shield from X-ray in medical examinations, such as CTs, mostly as it is considered non-toxic.
