Description
Manganese Dioxide Properties
Product Performance of Manganese Dioxide MnO2 CAS 1313-13-9:
Physical properties: black amorphous powder, or black rhombic crystals. Solubility: Difficult to dissolve in water, weak acid, weak base, nitric acid, cold sulfuric acid, and dissolve in concentrated hydrochloric acid under heating to produce chlorine gas.
Chemical properties:Manganese dioxide is an amphoteric oxide. There is a corresponding salt in the form of a perovskite structure such as BaMnO3 or SrMnO3 (obtained by a compound reaction in a molten alkali system). There is also manganese tetrachloride.
When meeting the reducing agent, it shows oxidizing property. If manganese dioxide is placed in a stream of hydrogen and heated to 1400K to obtain manganese oxide; manganese dioxide is heated in a stream of ammonia to obtain brown-black manganese trioxide; reacting manganese dioxide with concentrated hydrochloric acid produces l chloride Manganese chloride, chlorine and water.
When it meets strong oxidant, it also shows reducing property. It is a strong oxidant in acid medium.

Manganese Dioxide Application:
Used as a depolarizer for dry batteries, as a catalyst and oxidizer in the synthetic industry, as a colorant, decolorizer, iron remover, etc. in the glass industry and enamel industry. Used to manufacture metal manganese, special alloys, ferromanganese castings, gas masks and electronic materials ferrite. In addition, it can also be used in the rubber industry to increase the viscosity of rubber. It can also be used as a catalyst in chemical experiments.

Storage Condition of Manganese Dioxide MnO2 Powder:
Precautions for storage: Store in a cool, ventilated warehouse. Keep away from fire and heat. It should be stored separately from combustibles (combustibles), reducing agents and acids, and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage.
