Used as a precursor in the production of manganese-based catalysts for industrial oxidation processes, including organic synthesis such as phenol production and plastic precursors. Commonly employed in the synthesis of manganese dioxide and other manganese oxides used in batteries, particularly lithium-ion, alkaline batteries, and supercapacitors. Applied in ceramic and glass manufacturing to color or decolorize products, remove impurities, and reduce air bubbles. Utilized in the treatment of metal surfaces to improve corrosion resistance and as an additive in fertilizers to correct manganese deficiency in soils, promoting growth in crops and fruit plants. Also serves in the preparation of catalysts for the automotive industry to reduce emissions.
