Electric Area Fine Manganese Dioxide Powder Formula MnO2 With 99% Purity

 

Manganese dioxide is a black or brown solid, often found in pyrolusite and manganese nodules. Manganese dioxide (nature exists in pyrolusite form), molecular formula: MnO. The density is 5.026, insoluble in water and nitric acid. In hot concentrated sulfuric acid, oxygen is released into manganese sulfate. The release of chlorine in hydrochloric acid and manganese chloride and caustic alkali and oxidant eutectic, emit carbon dioxide and potassium permanganate is a strong oxidant; widely used in steelmaking, and used in making glass, ceramics, enamel, battery etc.. It is also often used as a catalyst in chemical reactions. A total of 500000 tons of pyrolusite was used in 1967. Manganese dioxide is often used to make Potassium Permanganate (KMnO4). It is often used as an oxidant in organic chemistry. Remember to prevent inhalation and eating, although no special protection is needed, oxidation is not strong enough. If it is blended to 15%, the danger will be reduced. There is basically no danger.
