Description

Cobalt Sulfate Heptahydrate is a high-purity inorganic salt essential for delivering bioavailable cobalt ions in critical industrial and nutritional applications. Its consistent quality and solubility make it a vital precursor in the manufacture of catalysts, pigments, and animal feed supplements. This product is primarily utilized by manufacturers in the battery, ceramics, agriculture, and chemical synthesis sectors seeking a reliable source of cobalt.

Application

• Animal Nutrition & Feed Additives: A critical source of cobalt for vitamin B12 synthesis in ruminants, preventing deficiency and promoting healthy growth.
• Electroplating & Surface Treatment: Used in electroplating baths to deposit hard, wear-resistant, and decorative cobalt or cobalt-alloy coatings on metal substrates.
• Catalyst Manufacturing: Serves as a key raw material in the production of catalysts for petroleum refining, hydrodesulfurization, and other chemical processes.
• Pigments & Dyes: Imparts stable blue and green colors in the production of ceramics, glass, paints, and inks.
• Rechargeable Battery Precursor: Used in the synthesis of cathode materials, particularly for lithium-ion batteries, contributing to energy density and stability.
• Agricultural Micronutrient: Formulated into fertilizers and soil amendments to correct cobalt deficiencies in crops and pasturelands.
• Chemical Synthesis: Acts as a starting material or reagent in various organic and inorganic synthesis routes.
• Drying Agent: Employed in paints, varnishes, and inks as a siccative to accelerate the drying process through oxidation.
