Used in electroplating processes to produce wear-resistant and decorative cobalt coatings on metals. Serves as a precursor in the synthesis of catalysts for petroleum refining and chemical manufacturing. Employed in rechargeable battery materials, particularly in lithium-ion battery cathodes, due to cobalt’s role in enhancing energy density and stability. Applied in animal feed as a source of essential cobalt for ruminants, supporting vitamin B12 synthesis. Utilized in pigment production for ceramics and glass, imparting deep blue colors. Also functions as a drying agent in paints and inks.
