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, brittle metal, 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.
The micro-nano bismuth powder is prepared by vapor phase evaporation and condensation method, with high purity, high sphericity, small bulk density, uniform particles, narrow distribution range, large specific surface area, high surface activity, spherical shape, good dispersion, high oxidation temperature, sintering Good shrinkage.
Application of nano bismuth powder
1. Nano metal lubricating additives: add 0.1~0.5% micro-nano bismuth powder to the lubricating grease to form a self-lubricating and self-repairing film on the surface of the friction pair during the friction process, which significantly improves the performance of the grease;
2. Metallurgical industry: micro-nano bismuth powder can be used as an additive for cast iron, steel and aluminum alloys to improve the cutting performance of alloys;
3. Magnetic material: Bismuth has a small thermal neutron absorption cross-section, low melting point and high boiling point, which can be used as a heat transfer medium for nuclear reactors;
4. Nano-alloy: micro-nano bismuth powder, with small particle size, high purity, high sphericity, and low melting point. It can be applied to alloy materials at present to refine the crystal structure of alloy materials, so that the mechanical properties of alloy materials are improved, and the alloy is reduced at the same time. The sintering temperature of the material.
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.
