Nickel-cobalt alloy is a permanent magnet material, which is widely used in electronic remote control, atomic energy industry and ultrasonic technology. In the chemical industry, nickel is often used as a hydrogenation catalyst.
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 and formed suitable nickel particles in the presence of gas additives (oxygen and nitrogen) by controlling temperature. The 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.
