Nickel Powder

Symbol: Ni

Atomic number: 28

Atomic weight: 58.6934

Element category: transition metal

Nickel is silvery-white. hard, malleable, and ductile metal. Pure nickel shows a significant chemical activity, but larger pieces of the metal are slow to react with air due to the protective oxide surface.

high melting point, 1453 ºC

Resists corrosion and oxidation

Very ductile

Alloys effectively

Magnetic at room temperature

Nickel powder is a kind of material with a variety of characteristics and wide application, as a kind of metal powder, it can be called one of the common materials in the field of powder metallurgy.

Nickel powder is a fine, granular substance, usually grayish black or dark cyan. Nickel powder has good chemical stability, electrical conductivity and thermal conductivity. In addition, nickel powder also has good ductility, plasticity and antioxidant properties. In the absorption of hydrogen, nickel powder has a very high activity, so it can be used as one of the materials of hydrogen storage alloys.

1. Battery: Nickel powder is widely used in electrode materials to make nickel-metal hydride batteries and nickel-lithium batteries.

2. Powder metallurgy: Nickel powder is used as a raw material of alloy powder in powder metallurgy, which can be made into alloy materials with high strength, high hardness and high corrosion resistance.

3. Spraying material: Nickel powder can be sprayed onto various metal, plastic, glass and ceramic surfaces to form a film with corrosion resistance, wear resistance and high temperature resistance on the surface.

4. Catalyst: Nickel powder can be used as a catalyst carrier to promote the chemical reaction. For example, nickel powder can be used in catalytic cracking and hydrogenation reactions.
