Superfine spherical nickel powder and preparation method thereof

The invention relates to the field of inorganic powder, and particularly discloses superfine spherical nickel powder and a preparation method thereof. The superfine spherical nickel powder is spherical, the particle size distribution ranges from 80 nm to 120 nm, and the content of Ni is 97% or above. By strictly controlling the process parameters, the particle size of the nickel powder product can be intensively distributed below 100nm, the particle size is small, the particles are uniform, and the technical difficulty of the industry is overcome; meanwhile, the particle size distribution of the nickel powder product is narrow, the difference between the maximum particle size and the minimum particle size is only 40 nm, an expensive grading device is not needed for grading, large-scale industrial production is achieved, and the production cost is reduced. In addition, the nickel powder product is high in nickel content, few in impurities and better in quality. 本发明涉及无机粉体的领域，具体公开了一种超细球状镍粉及其制备方法；一种超细球状镍粉，所述镍粉呈球形
