Due to the special small size effect of nano-nickel powder, it can be used as a catalyst to have many times higher catalytic efficiency than ordinary nickel powder, and is widely used in the hydrogenation of organic matter.

Because of its small particle size and physical magnetism, nano-nickel powder is widely used in the field of biomedicine as a magnetic material, as a carrier of various anti-cancer drugs, forming a magnetic targeted drug delivery system; made of nano-nickel powder magnetically The magnetic microspheres can also be widely used in the separation of magnetic immune cells and MRI imaging. The use of nano-nickel powder magnetism can generate heat under the action of an alternating electromagnetic field to kill tumor cells and achieve the purpose of treating tumors.
