New materials and energy

Nanoscale cobalt carbonyl powder, derived from cobalt carbonyl, has wide applications in energy storage (such as battery materials), the electronics industry (such as conductive pastes), and metal processing.

Metal refining and surface treatment

This compound can be used to refine high-purity cobalt metal. It is also used as a coating for metal surfaces to provide protection or specific functions, such as in CVD applications.

Precautions

1. Cobalt carbonyl should be sealed, protected from light, and stored in a dry environment at low temperature (2-8℃) to avoid decomposition and oxidation caused by air and moisture. It is recommended to store it in an inert atmosphere.

2. This product is highly flammable, with a flash point of only -13 °C. It must be kept away from open flames, heat sources, and oxidizers. Smoking and open flames are strictly prohibited in the work area, and explosion-proof facilities must be provided.

3. Protective glasses, gloves, and respirators should be worn during the operation to avoid direct skin contact.

4. If contact with skin, wash with plenty of water and soap. If contact with eyes, rinse immediately with water for at least 15 minutes and seek medical attention.

5. Waste should be treated as cobalt-containing hazardous chemicals and is strictly prohibited from being discharged into the environment or ordinary waste systems.
