Ultrafine Multi Functions Co Cobalt Nanoparticles

We are high-activity megnetic cobalt nanoparticles manufacturer.

Cobalt Nanopartilces is a high density magnetic recording materials and with multi-function .  

Nano Cobalt Powder have high density magnetic recording,high coercive force,high signal-to-noise ratio and oxidation resistance

Nano cobalt powder is magnetic, spherical, widely used in cemented carbides coating materials.

Cobalt nanopowder, 100-150nm, 99.9%,widely used as magnetic materials, or absorbing materials.

Nano cobalt wet powder, 20-30nm,100-150nm, 99.9%, more easy to dispersed and safe to transport out.

      Hongwu International Group LTD offer a highly diverse range of Cobalt particles grades with average grain sizes from approx. 20nm to 1um. We provide technical support in the selection of the powders suitable for specific applications. Stock# A050, 20NM Cobalt nano particles Stock# A051, 100-150NM Cobalt nano particles Stock# B052, 1-3UM Cobalt particles, grey solid powder.       Cobalt particle is the best binder for cemented carbide. Although iron, cobalt powder, nickel powder generations have made some progress, still more than 90% of the carbide cobalt used as binder. In order to improve the organizational structure of carbide, improve performance and reduce the size of cobalt powder has very important significance. To reduce the average particle size of the binder powder can improve the transverse rupture strength, hardness and density. To use the ultra-fine cobalt powder manufacturing high-performance WC-Co cemented carbide, requests the cobalt nano particles average particle size to achieve to less than 500nm. In such particle size could produce excellent adhesive. With the small particle size Cobalt powder to make WC-Co whose abrasion resistance and crack resistance is much better than the alloy produced with coarse cobalt powder.        If you're interested in cobalt nano particles, please feel free to contac us. by Lyla

Magnesium Oxide nano particles antibacterial 30-50nm         Magnesium Oxide nano particle(MGO) with a wide band-gap is an important inorganic material. MgO nano powder is a promising antibacterial agent because of its high resistance to harsh environment.  For the antibacterial ablity of MgO nano powder is related to the particle size. The antibacterial activity was increased with the decrease of the particle size of MgO nano. For particles in the size range 50-70 nm, the bactericidal efficacy of nano-MgO increased slowly with decreasing particle size. When the size under 40 nm, the bactericidal efficacy of MgO nano increases a lot and could kill more bacteria. This proves that the particle size is smaller the antibacterial efficacy of MgO is stronger. MgO nano particles penetrated the bacterial cell wall and cell membrane. For the size is smaller, and then killed more bacteria. Also MgO nano particles with large specific surface area increase as the size of the nano particles decreases. For the large surface area with lots of reactive groups on the particle surface and high antibacterial activity will be obvious.       Hongwu International Group Ltd is committed to provide high-quality Magnesium Oxide nano particles(30-50nm, 99.9%) with the most reasonable price for customers who are doing nanotech research and have formed a complete cycle of researching, manufacturing, marketing and after-sale servicing. Our products have been sold to many countries around the world.
