CAS 7440-69-9 Bismuth Powder Bi Metal Powder used for metallurgical industry
Brief Description of Bismuth Metal Powder
Bismuth is a chemical element with symbol Bi and atomic number 83.
Bismuth, a pentavalent post-transition metal and one of the pnictogens, chemically resembles its lighter homologs arsenic and antimony.
Elemental bismuth may occur naturally, although its sulfide and oxide form important commercial ores.
It is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge.
Bismuth is slightly radioactive and the most naturally diamagnetic element, and has one of the lowest values of thermal conductivity among metals.
Specification of Bismuth Metal Powder
Application of Bismuth Metal Powder
1.Metal nanometer lubricating additives: add 0.1 ~ 0.3% nanometer bismuth powder to grease, make the friction pair in the process of friction surface self-lubricating, self-healing membrane, significantly improve the performance of grease.
2. Metallurgical industry: nano bismuth powder can be used as cast iron, steel and aluminum alloy additive, improve alloy cutting performance.
3. Magnetic materials: bismuth minimal thermal neutron absorption cross section and the bottom of the melting point and high boiling point, can be used as a medium of heat transfer in the reactor.
This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.
