Description

Cobalt(II) Carbonate, Basic, Dihydrate is an inorganic salt that serves as a vital source of cobalt ions for a wide range of industrial and chemical synthesis processes. Its controlled basicity and consistent composition make it a preferred precursor for producing high-purity cobalt compounds and advanced materials. This product is essential for manufacturers in the ceramics, catalyst, and pigment industries, as well as for research and development in energy storage applications.

Application

• Catalyst Precursor: A key raw material in the synthesis of catalysts for petroleum refining, hydrodesulfurization, and Fischer-Tropsch synthesis.
• Pigments and Dyes: Used in the manufacturing of vibrant blue and green ceramic glazes, glass colorants, and artist's pigments.
• Animal Nutrition: Serves as a source of essential trace element cobalt in mineral feed supplements for ruminants.
• Electrode Materials: An important starting material in the production of lithium cobalt oxide (LiCoO₂) and other compounds for lithium-ion battery cathodes.
• Chemical Synthesis: Employed as an intermediate for producing various cobalt salts, such as cobalt acetate and cobalt sulfate.
• Driers for Paints & Inks: Acts as a catalyst (drier) to accelerate the oxidation and polymerization drying process in alkyd-based paints and printing inks.
