Description

Cobalt(II) Oxalate is an inorganic salt of cobalt and oxalic acid, serving as a critical precursor material in advanced industrial manufacturing. Its primary value lies in its role as an intermediate for producing high-purity cobalt metal, cobalt oxide, and other cobalt compounds essential for modern technology. This product is vital for manufacturers in the battery, catalyst, and pigment industries, where consistent quality and reliable supply are paramount for production efficiency.

Application

• Precursor for Cobalt Metal and Oxide Production: A key raw material in the synthesis of cobalt powders and cobalt oxides (CoO, Co3O4) via thermal decomposition.
• Lithium-Ion Battery Cathode Materials: Used in the preparation of lithium cobalt oxide (LiCoO2) and other cathode active materials for rechargeable batteries.
• Catalyst Synthesis: Serves as a starting material for manufacturing catalysts used in petrochemical refining, hydrogenation, and oxidation reactions.
• Pigments and Ceramic Glazes: Imparts stable blue and violet colors in ceramics, glass, and specialty paints.
• Animal Feed Additive (Cobalt Source): Processed into bioavailable cobalt salts used as a nutritional trace element in animal feed.
• Chemical Research and Synthesis: Employed as a reagent in laboratories for the preparation of novel coordination compounds and materials science research.

Quality Control

Our Cobalt(II) Oxalate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Production adheres to relevant industrial standards, with critical parameters including cobalt content, oxalate content, and specific impurity limits (e.g., heavy metals, chloride, sulfate) rigorously controlled. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with each shipment to guarantee product integrity for your application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept away from strong acids and strong oxidizing agents.
