Ultra-fine cobalt carbonate in the Japanese market: projected to reach 123 million USD by 2026, with a growth rate of 6.4%.
What is ultrafine cobalt carbonate? Ultrafine cobalt carbonate is a cobalt compound characterized by fine particles, produced through processes such as precipitation, washing, filtration, drying, and grinding/classification from cobalt salt aqueous solutions. It is generally supplied as a fine powder ranging from pink to reddish-purple, with small particle sizes, excellent dispersibility and reactivity, and a tendency to achieve stable sintering and reduction behavior in subsequent processes. In quality evaluation, important factors include cobalt content, median particle size (D50), specific surface area, bulk density, as well as the concentration of impurities such as sodium, chlorine, and sulfates, and variability between batches. Particularly, to achieve both fine particle size and low impurity levels, it is essential to control precipitation reactions and crystal growth, optimize washing conditions, and refine drying and classification processes.

Applications/Examples of results
Expansion of Demand for Battery Materials and Cemented Carbide Ultrafine cobalt carbonate is used in the production of fine cobalt powder, cobalt(III) oxide, cobalt oxide, precursors for cathode materials for lithium-ion batteries, and cobalt powder for the bonding phase of cemented carbide. Catalysts, ceramic pigments, magnetic materials, and electronic chemicals are also major applications. In cemented carbide, the particle characteristics of raw materials and impurities affect the microstructure and mechanical properties after sintering, so stable raw material quality is emphasized. In the field of battery materials, quality control capable of producing high-purity cobalt salts and cobalt-based precursors is also required. Since the purity and particle size required vary by application, appropriately designing grades for industrial, battery, and electronic materials will lead to an increase in product added value.
