Cobalt powder Description
Cobalt powder is a fine powder composed of small particles of the chemical element cobalt. It is malleable, magnetic, and has a high melting point. It appears as a gray, irregular powder, is soluble in acid, possesses magnetic properties, and easily oxidizes in humid air.
Cobalt powder is used in various applications, including the production of magnets, batteries, pigments, and catalysts. It can also be used as a precursor for other cobalt compounds and as a raw material in metal alloys. Due to its ability to absorb and emit radiation, cobalt powder is used in the field of nuclear technology for shielding and radiation therapy.

Cobalt powder Applications
Cobalt-based alloys or cobalt-containing alloy steels are used in blades, impellers, ducts of combustion gas turbines, jet engines, rocket engines, missile components, various high-load heat-resistant parts in chemical equipment, and as important metallic materials in the nuclear industry.
As a binder in powder metallurgy, cobalt ensures that hard alloys possess a certain level of toughness. There are three development trends for cobalt powder used in hard alloys: ultra-fine cobalt powder, nano WC-Co powder, and spherical cobalt powder.
Cobalt is also an important component of permanent magnetic alloys. Magnetic alloys are indispensable materials in modern electronics and electromechanical industries, used to manufacture various components for devices related to sound, light, electricity, and magnetism.
In the chemical industry, in addition to being used in high-alloy and corrosion-resistant alloys, cobalt is employed in colored glass, pigments, enamels, as well as in catalysts and desiccants.
The application of cobalt in batteries is noteworthy, particularly due to the widespread use of lithium-ion batteries, which has significantly increased the demand for cobalt. In nickel-metal hydride batteries, foam nickel electrodes doped with ultra-fine cobalt powder exhibit higher discharge capacity and stable cycling performance under high current charge and discharge conditions.
Cobalt powder is used in the petroleum industry's leaded cracking process, primarily as a catalyst for petroleum dehydrodesulfurization. With the advancement of nanotechnology, it has been discovered that nanocobalt powder has a catalytic effect on the thermal cracking process of polycarbosilanes and can reduce the cracking temperature.
