Hard Alloy Nano Grade Cobalt Powder, Nano Metal Cobalt Wet Powder
Nano-cobalt powder is a new functional materials, has high catalytic activity, surface activity, good sintering performance, high saturation magnetization, coercive force, etc., are widely used in cemented carbide, magnetic fluid, magnetic materials, battery, diamond tool manufacturing and other industries, and in ceramics, catalysis, magnetic materials, hydrogen storage alloy electrodes and specialty coatings and other areas exhibit many excellent properties. Nanoscale cobalt powder to reduce porosity of cemented carbide, to avoid the formation of cobalt pool, but also in the surface of the adhesive layer of the tungsten carbide cobalt powder, tungsten carbide grain size is conducive spaced, which helps to improve mechanical Carbide performance, and carbide with cobalt powder general requirements impurities and oxygen content is low, the small size of the spherical cobalt powder.
Addition of a surfactant can significantly improve the performance of nano-cobalt powder dispersed in ethanol, and at the same time, the addition of surfactants cobalt powder dispersion are better than no added surfactant cobalt powder.
Elemental nano metal cobalt powder, 20-30 nm, high surface activity, for safety use of incomplete drying manner, that contain some water, will accurately measure the moisture content of each. This helps customers scattered, but also to ensure safety and to be covered according to the customer needs to do with customer specified solvents replace water, completely dry surface treatment to be done, not only will affect the purity, not a good dispersion. We recommend ordering a half wet and dry powder.
