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 in coatings, catalyst, and battery material supply chains.

Where is Cobalt hydroxide used?

• Coatings and adhesives: drier precursor and catalyst activator
• Alkyd and oil-based systems: accelerates oxidative crosslinking
• Battery and energy materials: direct precursor to cobalt oxide and lithium cobalt oxide cathode materials
• Mining and hydrometallurgy: intermediate in cobalt refining circuits where pH adjustment drives selective precipitation from leach solutions
• Textile and paper processing: catalytic bleaching and pH buffer in wet-chemistry stages
• It serves as a primary source of cobalt ion activity in systems requiring controlled reactivity or conversion to downstream cobalt compounds.

Commercial specifications

• Moisture content and cobalt assay are the primary specification parameters buyers evaluate.
• Technical grade: purity typically expressed as minimum cobalt content by weight.
• Battery-grade material: tighter particle size distribution and trace metal controls for cathode precursor specifications.
