Main feature
Nano cobalt powder and ultra-fine cobalt powder are prepared by variable current laser ion beam gas phase method, with narrow particle size distribution range, controllable size, soluble in acid, magnetic, easy to oxidize in humid air, easy to disperse and industrial application.
Application field
1 High-density magnetic recording materials use nano cobalt powder to record high density, high coercivity (up to 119.4KA/m), high signal-to-noise ratio and good oxidation resistance, which can greatly improve magnetic tapes and large-capacity soft and hard disks. Performance;
2 Magnetic fluid The magnetic fluid produced from iron, cobalt, nickel and their alloy powders has excellent performance and can be used in sealing and shock absorption, medical equipment, sound adjustment, light display, etc.;
3 Wave absorbing material Metal nano powder has a special absorption effect on electromagnetic waves. Iron, cobalt, zinc oxide powder and carbon-coated metal powder can be used as high-performance millimeter wave invisible materials for military use, visible light-infrared invisible materials and structural invisible materials, and mobile phone radiation shielding materials;
4Ultra-fine cobalt powder is used as metallurgical products such as cemented carbide, diamond tools, high-temperature alloys, magnetic materials, and chemical products such as rechargeable batteries, industrial blasting agents, rocket fuel and medicine;
5Used in aviation, aerospace, electrical appliances, machinery manufacturing, chemical and ceramic industries. Cobalt-based alloys or cobalt-containing alloy steels are used as blades, impellers, ducts, jet engines, rocket engines, missile components and various high-load heat-resistant components in chemical equipment and important metal materials in the atomic energy industry. As a binder in powder metallurgy, cobalt can ensure the toughness of cemented carbide. Magnetic alloy is an indispensable material in modern electronics and electromechanical industry, used to make various components of sound, light, electricity and magnetism. Cobalt is also an important component of magnetic alloys. In the chemical industry, in addition to high-alloy and anti-corrosion alloys, cobalt is also used in colored glass, pigments, enamels, catalysts, and desiccants.
Packaging and storage
This product is in inert gas anti-static packaging and should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time to prevent agglomeration due to moisture, which will affect the dispersion performance and use effect.
