Cobalt nano powder refers to cobalt nano particles with an average particle size of less than 100nm. Nano cobalt powder is difficult to be accurately measured in laser particle size analyzer because of its very small particle size. Therefore, the particle size of nano cobalt powder is generally measured and judged intuitively by scanning electron microscope (SEM).

Nano cobalt powder should be sealed and stored in a dry and cool environment, and should not be exposed to the air for a long time to prevent moisture and agglomeration, affecting the dispersion performance and use effect. In addition, heavy pressure should be avoided, and contact with oxidants should not be allowed.

Cobalt Nanopowder Application

Nano cobalt powder is mainly used in magnetic recording materials, magnetic fluids and microwave absorbing materials. The details are as follows:
1. High density magnetic recording materials
Magnetic recording materials made of nano cobalt powder have the advantages of high recording density, high coercivity, high signal-to-noise ratio and good oxidation resistance, which can greatly improve the performance of magnetic tapes and large capacity soft and hard disks.
2. Wave absorbing materials
Nanometer iron, cobalt, zinc oxide powder and carbon coated metal powder can be used as high-performance millimeter wave stealth materials for military use, visible light infrared stealth materials, structural stealth materials, and radiation shielding materials for mobile phones.
