Description

Cobalt sulfate (CAS 10124-43-3 ), also known as cobalt monosulfate, is an inorganic cobalt salt used across electroplating, battery manufacturing, and agricultural micronutrient applications. It serves as a primary cobalt source in processes requiring controlled cobalt ion delivery at industrial scale. In electroplating and surface finishing, it is used in bath formulations to deposit cobalt. These cobalt-alloy coatings improve hardness and wear resistance on metal components. Battery and energy storage manufacturers use it as a precursor in synthesizing cathode active materials for lithium-ion chemistries. In agriculture, it is applied as a micronutrient supplement in fertilizers and animal feed to address cobalt deficiencies in livestock and soil. This ensures proper health and growth in various environments. Catalyst producers also use this chemical as a precursor for cobalt-based catalysts in hydroprocessing and chemical synthesis operations. It is a versatile component for many high-tech industrial sectors. The material is supplied primarily as a heptahydrate crystalline solid, with the anhydrous form available for specific technical applications. Standard commercial grades include technical grade and battery-grade. Battery-grade material is subject to tighter purity specifications relevant to cathode precursor production. Packaging typically ranges from small drums to bulk quantities for large-volume industrial buyers. Contact us for supply of Cobalt sulfate Request Quote
