Bismuth is still a common additive for industrial lubrication, and it works effectively without causing toxicity or other hazards to the specified compound. When added 0.1% to 0.3% of nano Bi powder to greases in the friction process, the friction surface will form a self-lubricating mask to protect the machine, it will significantly improve the grease performance.
Nuclear heat transfer
The unique mixture of magnetic, thermal and other properties in bismuth nanoparticles makes this powder the best heat transfer medium for nuclear reactors-only the most suitable material can function. As proof of the potential of this field, it is difficult to find more impressive applications.
Bismuth has a smaller thermal neutron absorption cross-section, lower melting point, and higher boiling point, which enable it to be the heat transfer medium used in a nuclear reactor.
Medical imaging agent
Bismuth nanopowder can be used as an effective contrast agent for medical imaging and some forms of cancer treatment, making it one of the most widely studied nanoparticles. Further medical applications are currently being studied and offer great hope.
Bismuth nanopowders have been widely used in metallurgy In metallurgy, bismuth is an effective alloying agent for the production and connection of certain metals. Nano Bi powder is used as additives during the production of cast iron, steel and Al alloy, which can improve the cutting performance of the alloy.
