Description

Cobalt Nitrate CAS NO 10141-05-6 is an inorganic salt of cobalt, commonly encountered as a hexahydrate. It serves as a versatile and essential precursor for the synthesis of high-purity cobalt compounds and catalysts. This product is critical for manufacturers in the ceramics, catalyst, and surface treatment industries seeking a reliable source of soluble cobalt ions.

Application

• Catalyst Manufacturing: A key raw material in the production of catalysts for petroleum refining, hydrodesulfurization, and other chemical synthesis processes.
• Ceramic Pigments & Glazes: Imparts stable blue and violet colors in porcelain, pottery, and specialty glass formulations.
• Surface Treatment: Used in electroplating and conversion coating baths to deposit cobalt or cobalt-alloy layers for wear and corrosion resistance.
• Precursor for Cobalt Oxide: A primary starting material for the thermal decomposition production of cobalt(II,III) oxide (Co3O4) and other cobalt oxides used in batteries and electronics.
• Agricultural & Nutritional Supplements: Source of cobalt in animal feed additives and fertilizer micronutrients to prevent cobalt deficiency.
• Laboratory Reagent: Used in analytical chemistry, research, and educational settings for qualitative and quantitative analysis.
• Drying Agent: Functions as an oxidative drier in certain paints, inks, and varnishes.
