Properties and Applications of Manganese Dioxide Nanoparticles
Nano-manganese dioxide, also called manganese oxide Nanoparticles (HN-MnO2-50), is an inorganic compound with the chemical formula MnO2. It is a black amorphous powder or black orthorhombic crystal. It is insoluble in water, weak acids, weak bases, x acids, Cold L acid dissolves in concentrated Y acid under heating to produce L gas. Used in the preparation of manganese salts, and also used as oxidants, rust removers, and catalysts. Acidity and alkalinity: Manganese dioxide is an amphoteric oxide. It is a black powdery solid that is very stable at room temperature and can be used as a depolarizing agent for dry batteries. In the laboratory, its oxidizing property is often used to react with concentrated HCl to produce L gas.
The nano-manganese dioxide produced by UrbanMines Tech. Limited is a black amorphous powder or black orthorhombic crystal. It is a stable oxide of manganese and often appears in pyrolusite and manganese nodules. The main use of nano-manganese dioxide is to manufacture dry batteries, such as carbon Zinc batteries and alkaline batteries are also often used as catalysts in chemical reactions or as strong oxidants in acidic solutions. Nanomanganese dioxide is a non-amphophilic oxide (non-salt-forming oxide). It is a black powdery solid that is very stable at room temperature and can be used as a depolarizing agent for dry batteries. It is also a strong oxidant and does not burn itself, but it does support combustion. Do not place it together with flammable materials.
Main applications of nano-manganese dioxide (HN-MnO2-50):
1. Nano-manganese dioxide (HN-MnO2-50) is mainly used as a depolarizing agent in dry batteries. Manganese dioxide is also a very good decolorizing agent in the glass manufacturing industry. It can oxidize low-price iron salts into high-iron salts. Turn the blue-green in the glass into a weak yellow. Used in the electronics industry to make manganese-zinc ferrite magnetic materials. It is used as a raw material for iron-manganese alloys in the steelmaking industry and as a heating agent in the casting industry. Absorbent for T monoxide in anti-virus equipment. In the chemical industry, it is used as an oxidant, a catalyst for organic synthesis, and a desiccant for paints and inks. It is also used as a combustion accelerant in the match industry, as a glaze for ceramics and enamel, and as a raw material for manganese salts. It is also used in fireworks, water purification and iron removal, medicine, fertilizer and fabric printing and dyeing.
2. Nano-manganese dioxide (HN-MnO2-50) is used in zinc-manganese batteries; alkaline manganese type is suitable for alkaline zinc-manganese batteries, and mercury-free alkali manganese type is suitable for alkaline zinc-manganese dioxide batteries. Nano manganese dioxide (HN-MnO2-50) is an excellent depolarizing agent for batteries. Compared with dry batteries produced by ordinary manganese dioxide, it has the characteristics of large discharge capacity, strong activity, small size, and long life. Therefore, Nanomanganese dioxide has become a very important raw material for the battery industry.
3. In addition to being the main raw material for batteries, nanometer manganese dioxide (HN-MnO2-50) is also widely used in other fields, such as: as an oxidant in the production process of fine chemicals and as a raw material in manganese-zinc ferrite soft magnetic materials.
4. Nano-manganese dioxide (HN-MnO2-50) has strong catalytic, oxidation/reduction, ion exchange and adsorption capabilities. After treatment and molding, it is an excellent water purification filter material with comprehensive performance, and Compared with commonly used water purification filter materials such as activated carbon and zeolite, it has stronger decolorization and metal removal capabilities.
