Used as a precursor in the production of manganese-based catalysts for industrial oxidation processes. Commonly employed in the synthesis of manganese dioxide and other manganese oxides used in batteries, particularly lithium-ion and alkaline batteries. Applied in ceramic and glass manufacturing to color or decolorize products and to improve resistance to heat and shock. Utilized in the preparation of catalysts for the production of synthetic rubber and in the oxidation of organic compounds. Also used in surface treatment processes for metals, enhancing corrosion resistance and adhesion properties in coatings.
