It can also be reduced when it comes into contact with strong oxidants. When manganese dioxide and potassium carbonate or potassium nitrate are combined and melted, you can get a dark green melting solution. This can be dissolved into water and cooled to produce potassium manganate which is a compound containing hexavalent magnese. It is a strong acid medium oxidant. Strong oxidizer. It does not burn by it self, but supports combustion. Do not combine it with flammable substances.
The primary function of manganese dioxide MnO2
Manganese dioxide is mostly used in dry batteries as a depolarizing agents. Manganese oxide is also an excellent decolorizing agent for the glass industry. It can turn low-valent iron sodium salts into high iron salts. Use in electronics industry to create manganese zinc ferrite magnetic materials. This is used as a raw ingredient in iron-manganese alloys in the steelmaking process and as a heat-increasing material in the casting industry. A gas mask absorbent that reacts with carbon monoxide. It is used in chemical industries as an oxidant and as a catalyst for organic synthesizing. It is also used in the match trade as a combustion aid, as well as as a raw ingredient for ceramics, enamel glazes and manganese sulfates. It’s also used for fireworks, water purification, iron removal, medicine and textile printing and dyeing.
Dilute hydrochloric Acid will not react with manganese dioxide. Concentrated hydrochloric acids have a large concentration of H+/Cl-, which has strong reducibility. It can be oxidized using MnO2 under heat to form Cl2. As the reaction progresses, it gradually decreases in H+ and Cl. As the reducibility decreases, MnO2 is unable to oxidize Cl. Dilute hydrochloric and manganese dioxide will not react. Hot concentrated sulfuric acids releases oxygen to form manganese-sulfate. Mix caustic soda, oxidant and co-melt to make manganate. It dissolves in acetone.
The electrolytic manganese oxide can be divided into three types: the mercury-free alkaline and alkaline type. The alkaline manganese is suitable to alkaline zinc batteries. The alkaline manganese is suitable for the zinc manganese alkaline batteries. While the ordinary type is good for zinc manganese, the alkaline manganese is suitable only for alkaline batteries. A manganese dioxide battery.
Application fields for manganese dioxide MnO2
The best battery depolarizer is electrolytic magnese dioxide. It is a superior battery depolarizer than dry manganese dioxide batteries. It has large discharge capacities, high activity, small sizes, and long lives. It is therefore an important raw material for industry.
The main raw material for batteries is electrolytic manganese dioxide. However, it has been extensively used in other areas such as oxidizers and raw materials in manganese zinc ferrite soft magnetic materials. It is capable of strong catalysis and oxidation / decrease, as well as ion exchange, and adsorption. After treatment and molding, it is a water purification material with excellent performance. It is more resistant to metal removal than water filter media.
