Cobalt sulfate heptahydrate
Description
Cobalt sulfate heptahydrate (CAS 10026-24-1), also known as cobaltous sulfate heptahydrate, is a water-soluble cobalt salt supplied primarily as a crystalline solid. It functions as a source of bioavailable cobalt across agricultural, industrial, and specialty chemical applications.
In agriculture, it corrects cobalt deficiencies in livestock feed formulations and soil amendment programs where ruminant health depends on adequate trace mineral intake. This ensures optimal growth and metabolic function in cattle and sheep.
Battery and electroplating industries use it as a cobalt source in electrodeposition baths and as a precursor in the synthesis of cobalt-based cathode materials. These applications are critical for the production of modern energy storage systems.
In catalyst manufacturing, it serves as a starting material for producing cobalt oxide and mixed-metal catalysts used in hydroprocessing and Fischer-Tropsch synthesis. These processes are essential for refining and chemical production.
Personal care formulators incorporate it at controlled levels in certain hair colorant systems where cobalt ions contribute to oxidative dyeing chemistry. This specialized use requires precise concentration management for safety.
Cobalt sulfate heptahydrate is supplied as pink-red crystalline granules or powder. Technical and feed-grade specifications are the most commonly traded forms, with purity levels typically ranging from 98% to 99%+.
Packaging is available in bags and drums suited to bulk industrial procurement. Our supply chain ensures consistent quality and reliable delivery for large-scale manufacturing and agricultural distribution networks.
