Description

Cobalt Citrate is a coordination compound of cobalt and citric acid, widely recognized for its role as a bioavailable source of cobalt. This compound is essential in applications where controlled cobalt delivery is critical, particularly in animal nutrition and specialized industrial processes. It is primarily utilized by manufacturers in the feed additive, catalyst, and fine chemical synthesis industries.

Application

• Animal Feed Additive: A vital trace mineral source in premixes for ruminants like cattle and sheep to support vitamin B12 synthesis and metabolic functions.
• Catalyst Precursor: Serves as a starting material in the synthesis of catalysts for oxidation and polymerization reactions.
• Nutrient Supplement: Used in the formulation of specialized fertilizers and hydroponic solutions to correct cobalt deficiencies in soils and plants.
• Laboratory Reagent: Employed in analytical chemistry and research as a standard or reagent for cobalt determination and complexometric studies.
• Ceramic & Pigment Intermediate: Acts as a component in the production of certain colored glasses, glazes, and ceramic pigments.
• Electroplating Solutions: Used in specific electroplating baths to deposit cobalt-alloy coatings with unique properties.
