The main characteristics of nano-cobalt powder, ultra-fine cobalt powder prepared through a special process, interval narrow particle size distribution, controllable size, soluble in acid, magnetic, easily oxidized in moist air, is easily dispersed and industrial applications.
Applications
A high-density magnetic recording materials using nano-cobalt powder high recording density, high coercivity (up to 119.4KA / m), signal to noise ratio and good oxidation resistance, advantages can be a significant improvement in tape and large-capacity hard and soft disk performance;
Two magnetic fluid iron, cobalt, nickel and its alloy powder production performance of magnetic fluid, can be widely used to seal the damping, medical equipment, sound adjustment, the light display;
Three absorbing materials metal nanopowder special role in the absorption of electromagnetic waves.Iron, cobalt, zinc oxide powder and carbon-coated metal powder as a military high-performance millimeter-wave invisible material, visible light – infrared stealth materials and structures invisible materials, as well as mobile phone radiation shielding material;
4 ultrafine cobalt powder used as a carbide, diamond tools, high temperature alloys, magnetic materials, metallurgical products, chemical products and rechargeable batteries, industrial blasting agents, rocket fuel, and medicine;
5 is widely used in aviation, aerospace, electrical appliances, machinery manufacturing, chemical and ceramic industry. Cobalt-based alloy containing cobalt alloy steel used for combustion turbine blades, impellers, catheters, jet engines, rocket engines, missile components and chemical equipment in a variety of metal materials for high heat-resistant components of the load and the atomic energy industry. Cobalt as a binder in powder metallurgy carbide have a certain toughness. The magnetic alloy is indispensable to modern electronics and electrical industry materials used to manufacture the various components of equipment such as sound, light, electricity and magnetism. An important part of cobalt permanent magnetic alloy. In the chemical industry, cobalt addition for high alloy and corrosion alloy used for colored glass, paint, enamel and catalyst, desiccant.
