Nickel powder
Nickel powder, also known as carbonyl nickel powder, is mainly used in coatings and plastics as conductive pigments to shield electromagnetic interference and radio frequency interference. It is also used as various high gloss decorative paints and plastics, replacing aluminum powder as anti-corrosion paint in water-based systems. Fine spherical nickel powder can be used for conductive inks.
Character: It is a gray irregular powder that is easy to oxidize in humid air.
Purpose: Used for producing non ferrous alloys, high-temperature resistant, antioxidant materials, magnetic materials, and as hydrogenation catalysts for chemical reactions.
Packaging: Packed in lined plastic bags, cloth bags, and iron drums filled with protective gas.
Metal pigments mainly composed of metallic nickel, including nickel powder and flake nickel powder. The former is decomposed by distillation and purification of carbonyl nickel [Ni (CO) 4] vapor, diluted with carbon monoxide and formed suitable nickel particles in the presence of gas additives (oxygen and nitrogen) by controlling temperature. The carbon monoxide is then washed away with carbon dioxide gas and the surface oxygen content of the particles is controlled to 0.065%; The latter is formed by grinding high-purity carbonyl nickel powder with steel balls in a ball mill in the presence of suitable lubricants and liquid media to form flakes of appropriate thickness.
Appearance quality
Carbonyl nickel powder should have uniform color, no clumping or agglomeration, and no visible inclusions
