Description

Cobalt Chloride CAS NO 7646-79-9 is an inorganic salt of cobalt, widely recognized for its role as a precursor in the synthesis of other cobalt compounds and as a source of cobalt ions. Its significance lies in its versatile chemical reactivity and its function as an indicator of humidity. This product is essential for manufacturers and researchers in sectors including catalysts, pigments, electroplating, and as a trace nutrient additive in animal feed.

Application

• Catalyst Manufacturing: A key precursor for synthesizing catalysts used in petroleum refining, hydroformylation, and other organic synthesis processes.
• Electroplating & Surface Treatment: Used in electroplating baths to deposit cobalt and cobalt alloy coatings for wear resistance and magnetic properties.
• Pigments & Dyes: Serves as a starting material for producing cobalt blue and other ceramic pigments and glass colorants.
• Animal Nutrition: Provides an essential source of cobalt, a vital trace element, in mineral premises for livestock feed.
• Humidity Indicators: Utilized in silica gel and other desiccants as a moisture-sensitive color indicator (blue when dry, pink when hydrated).
• Chemical Synthesis: Acts as a reagent or intermediate in the production of various cobalt salts, complexes, and coordination compounds.
• Research & Development: Employed in laboratories for analytical chemistry, electrochemistry, and materials science research.
