MnO2 Powder (MnO2), an inorganic compound with the chemical formula MnO2, exists in soft manganese ore. For black amorphous powder or black orthorhombic crystal, difficult to dissolve in water, weak acid, weak alkali, nitric acid, cold sulfuric acid, heating conditions dissolved in concentrated hydrochloric acid, and producing chlorine gas. Acid and alkaline: manganese dioxide is an amphoteric oxide, a very stable black powder solid at room temperature, and can be used as a depolarizing agent for dry batteries. The laboratory often uses its oxidation and concentrated HCl action to produce chlorine gas: manganese dioxide is a strong oxidant in acidic media. Manganese dioxide is an octahedral structure, with oxygen atoms at the top of the octahedral angle and manganese atoms in the octahedral; octahedrons are connected to form a single or double chain; these chains and other chains coop, forming the gap of the tunnel structure, the octahedron or into six dense square accumulation, or establish dense square accumulation. Manganese dioxide is an amphoteric oxide in the form of BaMnO3 or SrMnO3 perovskite structure (obtained by the reaction in the molten alkali system) and also in the presence of manganese tetrachloride. When encountering the reducing agent, it shows the oxidation property. If manganese dioxide is heated in the hydrogen gas flow to 1400K, manganese dioxide is heated in the ammonia air stream to obtain brown-black manganese trioxide; When manganese dioxide is reacted with concentrated hydrochloric acid, manganese chloride, chlorine gas, and water are obtained. When encountering a strong oxidant, it also shows a reduction. Suppose manganese dioxide, potassium carbonate, and potassium nitrate or potassium chlorate mixed melt. In that case, it can melt dark green, and melt in water cooling can get hexavalent manganese compound potassium manganese acid. It is a strong oxidant in acidic media.
Main uses of MnO2 Powder MnO2 Powder Can be used as a dry battery depolarization agent, synthetic industry catalyst, and oxidant, but also synthetic glass industry and enamel industry colorant, colorant, iron agent, etc. It is used to manufacture manganese metal, special alloys, manganese iron castings, gas masks, and ferrite electronic materials. In addition, it can also be used in the rubber industry to increase the viscosity of the rubber. It can also be used as a catalyst in chemical experiments. In the laboratory, MnO2 Powder is used as a catalyst for the decomposition of hydrogen peroxide to oxygen, as a catalyst for the decomposition of potassium chlorate to oxygen, and as an aluminum thermal reaction with simple aluminum powder to produce manganese. Used as a pigment, yellow glass, etc.; react with hot concentrated hydrochloric acid; react with molten caustic potassium (potassium hydroxide) in the air; and decompose potassium permanganate, manganese dioxide as self-catalyst for potassium permanganate.
