Metallic nickel, chemical symbol Ni, atomic number 28, density 8.902g/cm3, melting point 1453℃ and boiling point 2732℃. Nickel is a silvery white metal with good strength and ductility at low temperature. At room temperature, a dense oxide film will be formed on the surface in humid air, which can prevent further oxidation and easily form alloys with other metals. Nickel is an important industrial metal, which is widely used in iron and steel industry, machinery industry, construction industry and chemical industry. Specific uses include: first, as a metal material, including the production of stainless steel, heat-resistant alloy steel and various alloys; Secondly, when electroplating, a durable and corrosion-resistant surface layer is covered on the substrate of metal materials such as steel; Thirdly, it is used as a catalyst in the hydrogenation process of petrochemical industry; Fourth, it is used as a chemical power supply to manufacture nickel-hydrogen batteries and nickel-cadmium batteries; Fifth, make pigments and dyes, and make new materials such as ceramics and ferrite.
