It is mainly used as depolarizer in dry batteries. It is a good decolorizer in the glass industry. It can oxidize low-cost iron salt into high iron salt, so that the blue-green of glass turns to weak yellow. Manganese zinc ferrite magnetic materials are used in electronic industry. It is used as the raw material of iron manganese alloy in steel-making industry and the heating agent in casting industry. Chemicalbook is used as an absorbent of carbon monoxide in gas masks. In the chemical industry, it is used as an oxidant (such as purpurin synthesis), a catalyst for organic synthesis, and a desiccant for paints and inks. It is also used as a combustion promoter in the match industry, as a raw material for glaze medicine and manganese salt of ceramics and enamel. It is also used in the purification of fireworks and water, iron removal, medicine, fertilizer and fabric printing and dyeing.
