Used as a precursor in the synthesis of manganese-based catalysts, especially for oxidation reactions in industrial processes. Commonly employed in the production of manganese dioxide and other manganese oxides used in batteries, particularly alkaline and lithium-ion batteries. Serves as a catalyst in the manufacturing of ceramics and glass, helping to control color and improve clarity. Applied in surface treatment processes, such as phosphating of metals, to enhance corrosion resistance. Also utilized in the preparation of mixed metal oxide coatings and in environmental catalysts for the reduction of nitrogen oxides (NOx) emissions.
