How to Prepare Ultrafine Spherical Cobalt Powder

High-pressure water mist

Cobalt Pulp can be used to make cemented carbide, petrochemical catalyst, and hydrogen storage alloy electrode. A widely used spray process, it involves the activation of an induction furnace. The high pressure water-atomized cobalt liquid, which will be a large part of its melting, will escape through the bottom. From the atomization device the annular nozzle fluid from high pressure will separate into millions of small beads and droplets through condensation. Finally, after drying, dehydration and drying, nanometer Cobalt powder will be obtained.

Electrolytic Process

Electrolysis can prepare cobalt metal powder. The basic principle is that you use a cobalt plate and a high-polished stainless steel water jacket to act as cathodes. The electrolyte is usually cobalt chloride, or cobalt sodium aqueous solution. An electrolytic cell is powered by direct current. The electrolyte then becomes ionized. The cobalt ions form Cobalt powder at this point. A sufficient amount of active surface agent is added to the electrolyte in order to avoid the accumulation of Cobalt Powder.

Cobalt hydrogen oxide reduction

Cobalt Hydrogen Oxide Reduction is also used extensively in the preparation cobalt powder for cemented caride. This technique is primarily based on Co2O3, Co2O3 or CoO cobalt oxide as raw materials. Hydrogen at 400600 C is used to reduce the Cobalt Powder.
