How to Prepare Ultrafine Spherical Cobalt Powder

High-pressure water mist

Cobalt Powder has a wide range of uses due to its outstanding physical, chemical, and mechanical characteristics. This spray technique has been used extensively. The technological process is to activate the induction furnace. Once the cobalt melts into it, the liquid will leak into the package. In the end, the annular-nozzle fluid of high tension water will separate into small beads.

Electrolytic procedure

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 sulfate in an aqueous solution. An electrolytic cell receives 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 widely in the preparation cobalt powder for cemented caride. This technique is mainly based upon cobalt oxide (Co2O3, Co2O3 & CoO) and is used to prepare Cobalt Powder for cemented carbide.
