Cobalt hydroxide

Cobalt hydroxide (CAS 12672-51-4), also known as cobaltous hydroxide, is an inorganic cobalt compound used as a precursor and reactive intermediate across coatings, catalyst, and battery material supply chains. It serves as a primary source of cobalt ion activity in systems requiring controlled reactivity or conversion to downstream cobalt compounds. In coatings and adhesives, it functions as a drier precursor and catalyst activator.

This material accelerates oxidative crosslinking in alkyd and oil-based systems. Battery and energy material manufacturers use it as a direct precursor to cobalt oxide and lithium cobalt oxide cathode materials. In mining and hydrometallurgy, it appears as an intermediate in cobalt refining circuits, where pH adjustment drives selective precipitation from leach solutions. This process ensures high-quality output for industrial use.

Textile and paper processing operations use cobalt hydroxide for catalytic bleaching and as a pH buffer in specific wet-chemistry stages. It is supplied as a fine powder or wet cake for various applications. Moisture content and cobalt assay are the primary specification parameters buyers evaluate. Technical grade is the standard commercial form, with purity typically expressed as minimum cobalt content by weight.

Battery-grade material is available with tighter particle size distribution and trace metal controls to meet cathode precursor specifications. These standards ensure the material performs reliably in high-tech manufacturing.
