About Bismuth Nanoparticles Nano Bi Powder:
Bismuth nanoparticles are a kind of metal nanoparticles with colors from dark gray to black according to the different particle sizes. 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. Feel free to send an inquiry to get the latest price if you would like to buy Bismuth Nanoparticles Nano Bi Powder in bulk.

How is Bismuth Nanoparticles Nano Bi Powder produced?
The bismuth nanoparticles are synthesized via a solvothermal reduction method based on the chemical reduction of Bi3+ by ethylene glycol acting as the solvent and the reducing agent. Bismuth based nanoparticles were grown starting from a dispersed solution of the bismuth salt.

Application of Bismuth Nanoparticles Nano Bi Powder:

Lubricant additives
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.
Metallurgical Industry
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.

Storage Condition of Nickel Nanoparticles Nano Ni Powder:
Damp reunion will affect bismuth nanoparticles dispersion performance and using effects, therefore, nano Bi powder should be sealed in vacuum packing and stored in cool and dry room, the nickel nanoparticles can not be exposure to air. In addition, the Bi Nanoparticles should be avoided under stress.

Packing & Shipping of Nickel Nanoparticles Nano Ni Powder:
We have many different kinds of packing which depends on the bismuth nanoparticles quantity.
