Description

Cobalt (CAS 7440-48-4 ), commonly abbreviated as Co, is a transition metal supplied in elemental form for use across catalyst manufacturing and pigment production. It functions as a foundational raw material in processes requiring controlled oxidation states. This versatile metal is essential for applications involving magnetic properties or colorant precursors. In catalyst manufacturing, elemental cobalt serves as a precursor for Fischer-Tropsch synthesis catalysts used in gas-to-liquid fuel conversion. It is also utilized in hydroprocessing and various industrial chemical reactions. Pigment producers use cobalt to produce cobalt blue and cobalt violet colorants for cosmetic formulations, ceramics, and artist-grade materials. In personal care, cobalt-derived compounds contribute to preservative and antimicrobial systems in certain formulations. Pharmaceutical manufacturers use cobalt as a starting material for synthesizing cobalt-containing active compounds. These materials are also vital for micronutrient preparations and specialized medical applications. Elemental cobalt is available as powder, granules, pellets, and cathode or briquette forms to suit different downstream processing requirements. Standard purity grades range from technical to high-purity (99.8%+), with battery-grade and catalyst-grade specifications available for demanding applications. Quality control ensures consistency across various industrial batches. Powder particle size distributions are typically specified to match sintering, alloying, or dispersion requirements in end-use processes. This ensures optimal performance in metallurgical and chemical manufacturing environments. Contact us for supply of Cobalt Request Quote
