Nano materials-nano-scale bismuth powder

Overview of Nano Bismuth Powder

Nano-bismuth particles are metal nanoparticles. Depending on the size of the particles, the color varies from dark gray to black. The newly produced bismuth is a silvery, crystalline, fragile metal that is usually pink in the air. Bismuth is the most diamagnetic element, and its thermal conductivity is lower than any metal except mercury. It has high resistance and the highest Hall coefficient.

Nano-bismuth powder is synthesized by solvothermal reduction method, which is based on the chemical reduction of Bi3+ with ethylene glycol as solvent and reducing agent. Bi-based nanoparticles are grown from a dispersion solution of bismuth salt. Nano bismuth particles are a kind of light gray non-ferrous metal powder, which is widely used and mainly used for preparing bismuth products, bismuth alloys and bismuth compounds.

Application of nano bismuth powder

Lubricant additives

Bismuth is still a commonly used additive in industrial lubrication. It works effectively and does not cause toxicity or other hazards to specified compounds. When 0.1% to 0.3% of nano-bismuth powder is added to the grease during the friction process, the friction surface forms a self-lubricating mask to protect the machine, which significantly improves the performance of the grease.

Nuclear heat transfer

The unique combination of magnetic, thermal and other properties of bismuth nanoparticles makes this powder the best heat transfer medium for nuclear reactors, and only the most suitable materials can play a role. As a testament to the potential of this field, it is difficult to find impressive applications for more people.

Bismuth has a smaller thermal neutron absorption cross section, lower melting point and higher boiling point, making it a heat transfer medium for nuclear reactors.

Medical imaging agent

Bismuth nanopowders can be used as an effective contrast agent for medical imaging and certain 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

Nano-bismuth powder has been widely used in metallurgy. In metallurgy, bismuth is an effective alloying agent for the production and connection of certain metals. Nano-bismuth powder is used in the production of cast iron, steel and aluminum alloy. Additives can improve the cutting performance of the alloy.

Humid environment will affect the dispersion performance and use effect of nano bismuth powder. Therefore, the nano-bismuth powder should be sealed in a vacuum package and stored in a cool and dry room, and the nano-bismuth powder should not be exposed to the air.
