Properties, Storage and Cautions:

Cobalt nanopowder is highly reactive and flammable, therefore it should be handled with care and rapid moves, vibrations should be avoided.
Powder should be kept away from sunlight, any kind of heating, moisture and impacts. Coagulation of the particles is a serious problem, so,
Co powder should be sealed under vacuum and should be kept in cool and dry conditions. Air contact should be avoided. This product is
PARTIALLY PASSIVATED for safe shipping purpose, gives no performance effect. 


Co powder has electromagnetic wave absorbtion ability and it is a magnetic material. Therefore, it can be applied to EMI shielding, magnetic
inks and magnetic storage media. It can also be used in MRI chemical reagents.
