Cobalt sulfate is widely used in the electroplating industry to provide a durable and corrosion-resistant cobalt coating on metal surfaces. It serves as an essential component in the preparation of pigments, particularly cobalt blue for ceramics, glass, and textiles, imparting a distinctive blue color. In agriculture, it is utilized as a trace element additive in animal feed to ensure proper cobalt levels for vitamin B12 synthesis in livestock, and in fertilizers to address cobalt deficiencies in soil for plant growth. It is employed in the production of batteries, including lithium-ion, nickel-cadmium, and nickel-metal hydride types, to enhance performance, stability, and lifespan. Cobalt sulfate also finds application in the manufacture of catalysts for chemical reactions such as petroleum refining and organic synthesis, as well as in leather tanning processes and as a mordant in textile dyeing.
