Product Name: Manganese Oxide, Manganese Dioxide.
CAS number: 1313-13-9.
EINECS number: 215-202-6
Chemical formula: MnO2.
Molecular weight: 86.94.
Purity: 99.9%.
Particle size: millimeter level micrometer level, nanometer level (can be customized produced according to customer requirements).
Appearance: Black powder.
Characteristics: Manganese dioxide is a non amphoteric oxide (non salt forming oxide), which is a very stable black powdery solid at room temperature. Strong oxidant, does not burn on its own, but supports combustion. Difficult to dissolve in water, weak acids, weak bases, nitric acid, and cold sulfuric acid. When heated, it dissolves in concentrated hydrochloric acid and produces chlorine gas.
Application:
1.Used as a depolarizing agent in dry batteries. It is a good decolorizer in the glass industry, which can oxidize low valent iron salts into high valent iron salts, turning the blue-green color of glass into a weak yellow color.
2.Used in the electronics industry to make magnetic materials. Used as a heating agent for iron manganese alloy raw materials and casting industry in the steelmaking industry.
3.Used as oxidants, catalysts for organic synthesis, desiccants for paints and inks in the chemical industry.
4.Used as a combustion enhancer in the match industry, ceramic raw materials, water purification, fabric printing and dyeing, rubber industry, manufacturing of manganese metal, analytical reagents, special alloys, manganese iron castings, electronic material ferrites, etc.
5.Used as a disinfectant, oxidant, catalyst, etc. in various industries such as medicine (potassium permanganate), national defense, communication, electronic technology, printing and dyeing, photography, ceramics, matches, soap making, welding, water purification, agriculture, etc.
