Average particle size(um)is 2 Specific surface area(m 2 / g)is 0.96 Bulk density(g / cm 3) is 0.23 Polymorphs is Spherical

 Main characteristics of micro-iron, the preparation of ultrafine iron through a special process, uniform product particle size, narrow particle size distribution, high purity, low carbon, sulfur, phosphorus and other harmful elements, good fluidity, powder antioxidant capacity high, low sintering temperature, high purity and high, spherical, particle size control, black powder, average particle size of 30-80um, not coated with purity greater than 99.99%. High-performance magnetic recording materials, magnetic fluid, absorbing materials, magnetic slurry, micro-directing agent, extended the absorbing material.

 Applications 1An absorbing material: metal micropowder special role in the absorption of electromagnetic waves. Iron, cobalt, zinc oxide powder and carbon-coated metal powder as a military stealth materials of high-performance millimeter-wave, visible light, infrared stealth materials and structure of stealth materials, as well as mobile phone radiation shielding material; 2 Two magnetic slurry: the use of micro-iron, high saturation magnetization and high permeability rate characteristics, can be made of the magnetic slurry for bonding structure of the fine head, etc.; 3 Three high-performance magnetic recording materials: the use of micro-iron, high coercivity, saturation magnetization, the signal to noise ratio and good oxidation resistance, etc., can greatly improve the performance of the tape and large-capacity soft and hard disk; 4magnetic fluid: excellent performance of the magnetic fluid iron, cobalt, nickel and its alloy powder can be widely used to seal the damping, medical equipment, sound regulation, and the light show.
