Manganese dioxide (in the form of pyrolusite in nature), physical properties: Black amorphous powder, or black orthorhombic crystal, solubility: insoluble in water, weak acid, weak alkali, nitric acid and cold sulfuric acid, soluble in hot concentrated hydrochloric acid to produce chlorine.
1. It is mainly used as depolarizer in dry battery. It is a good decolorizer in the glass industry. It can oxidize low-cost iron salt into high iron salt and turn the blue-green of glass into weak yellow.
2. Manganese zinc ferrite magnetic materials used in electronic industry. It is used as the raw material of iron manganese alloy in steelmaking industry and the heating agent in casting industry. Used as an absorbent of carbon monoxide in gas masks.
3. In the chemical industry, it is used as oxidant (such as purpurin synthesis), catalyst for organic synthesis, and desiccant for paint and ink. It is also used as combustion supporting agent in match industry, glaze medicine of ceramics and enamel and raw material of manganese salt. It is also used for the purification of fireworks and water, iron removal, medicine, fertilizer and fabric printing and dyeing.
