Nickel, atomic number 28, is listed as Block D and Period 4 elements in the periodic table. It is particles of the black spherical high surface. Nickel nanoparticles are reactive nanoparticles, highly inflammogenic, and also highly redox-active. It can be gained in passivated, dispersed, coated, and high purity form as well. The most beneficial use of nickel nanoparticles is the catalysts in different chemical reactions. These nanoparticles are used as the solid propellants to enhance the combustion heat, stability, and efficiency. Being used as an additive, it decreases the sintering temperature of ceramics and metals. It is also successfully used to create plastics, nanowires, textiles, and nanofibers. The use of nickel nanoparticles as the automotive catalytic converters is very common. Nickel nanoparticles are being used as the propellant and sintering additive. Corrosion-resistant alloys are prepared by the help of nickel nanoparticles. Being electrically conductive, it is being used in the electrical field.
