Used as a catalyst precursor in chemical reactions, especially in hydrogenation and electrochemical processes. Employed in the production of nickel-based batteries and electronic components due to its electroactive properties. Serves as an intermediate in synthesizing other nickel compounds for industrial use. Applied in ceramic glazes and glass manufacturing to impart green or blue coloration. Also utilized in the preparation of nickel coatings and plating baths for corrosion resistance in metal finishing industries.
