Nano Manganese Dioxide

Product Characteristics:

CAS: 1313-13-9

Manganese dioxide is an inorganic compound with the chemical formula MnO2. It appears as a black amorphous powder or black orthorhombic crystal, insoluble in water, weak acids, weak bases, nitric acid, and cold sulfuric acid. It dissolves in concentrated hydrochloric acid when heated, producing chlorine gas. It is used in the preparation of manganese salts and also serves as an oxidizer, rust remover, and catalyst. Acidity and alkalinity: Manganese dioxide is an amphoteric oxide. It is a very stable black powdery solid at room temperature and can be used as a depolarizer in dry batteries. In laboratories, its oxidizing property is often utilized to react with concentrated HCl to produce chlorine gas.

Application Fields:

Main uses of manganese dioxide:

1. Used as a depolarizer in dry batteries, catalyst and oxidizer in the synthesis industry, coloring agent, decolorizing agent, and de-ironing agent in the glass and enamel industries. Used in the production of metallic manganese, special alloys, manganese iron castings, gas masks, and electronic materials such as ferrites. Additionally, it can be used in the rubber industry to increase the viscosity of rubber. It is also used as a catalyst in chemical experiments.

2. Organic synthesis applications.

3. Laboratory uses: as a catalyst for the decomposition of hydrogen peroxide to produce oxygen; as a catalyst for the decomposition of potassium chlorate when heated to produce oxygen; reacts with elemental aluminum in a thermite reaction to produce manganese. Used as a pigment, in yellow glass, etc.; reacts with hot concentrated hydrochloric acid to produce chlorine gas; reacts with molten caustic potash (potassium hydroxide) in air to produce potassium manganate; in the decomposition reaction of potassium permanganate, manganese dioxide acts as an auto-catalyst for potassium permanganate.
