Nano iron powder as absorbing material

  • July 25,2018.
      Nowadays nanoparticle material plays more and more important role in different areas. Today we would like to discuss about nano iron ( Fe ) powder especially nano iron powder as absorbing material.

      In the military, stealth technology is important means to improve the survival, penetration, and combat effectiveness of weapons systems, Modern war on the absorbing material of the wave performance requirements are getting higher and higher, and with the development of electronic technology, also more and more electromagnetic radiation appear in our life. Therefore, the superior nano-absorbing materials on the military and civilian are of great significance. The special structure of nanomaterial makes it a new bright spot for stealth technology. Because of its small size, large surface area, the interface polarization and multiple scattering become important absorbing mechanisms. Nano iron powder is a kind of absorbing material. Metal nano-powder for electromagnetic waves, especially high frequency to the frequency of light waves within the electromagnetic wave has an excellent, and nano iron has been the hot point in this research.

      Also nano iron powder can be applied as high-performance magnetic recording materials, using nanometer iron powder coercive force, high saturation magnetization intensity, high SNR, and the advantages of good oxidation resistance, can significantly improve the performance of tape and high-capacity soft hard disk.

      In addition, nano-iron powder can also be used for magnetic paste, magnetic fluid, nano-guide agent, efficient combustion agent, etc.
