Significant chemical properties of the MnO2 Powder 

What is the role of MnO2 Powder?
MnO2 Powder can be used as a dry battery depolarization agent, synthetic industry catalyst and oxidant, glass industry and enamel industry coloring agent, fading agent, iron removal agent, and so on. It is used to manufacture manganese metal, special alloys, manganese iron castings, gas masks, and ferrite electronic materials. Moreover, it can be used in the rubber industry to increase the viscosity of rubber; in chemical experiments as a catalyst for the decomposition of hydrogen peroxide to produce oxygen; as a catalyst for heating potassium chlorate to make oxygen; and in aluminum thermal reaction with simple aluminum powder to have 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 with potassium permanganate, MnO2 Powder as a catalyst for potassium permanganate.

What are the physical and chemical properties of MnO2 Powder?
With a melting point of 535℃ and a density of 5.03 g/cm3, MnO2 Powder is a black amorphous powder or a black orthorhombic crystal, insoluble in water. MnO2 Powder is an amphotropic oxide, a very stable black powder solid at room temperature, and can be used as a depolarizing for dry cells. When encountering the reducing agent, it shows the oxidation property. If MnO2 Powder is heated in the hydrogen gas flow to 1400K, MnO2 Powder is heated in the ammonia air stream to obtain brown-black manganese trioxide; when MnO2 Powder 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 the MnO2 Powder, potassium carbonate, and potassium nitrate or potassium chlorate mixed melt. In that case, it can get dark green melt, and the melt dissolved in water cooling can get hexavalent manganese compound potassium manganese acid. Is a strong oxidant in acidic media?
What are the precautions for the storage and use of MnO2 Powder?
MnO2 Powder is a strong oxidant that does not burn itself but helps combustion and can not be placed together with flammable materials. At the same time, excessive manganese in the body can cause poisoning. Significant damage to the central nervous system, especially acute poisoning in extrapyramidal industrial production, is rare. If a large amount of the smoke is inhaled quickly, "metal smoke heat" can occur, and the patient has headaches, nausea, chills, high fever, and big sweat. Chronic poisoning symptoms include neurasthenia syndrome, autonomic nerve dysfunction, mental symptoms of excitation and inhibition imbalance, and toxic psychosis; extrapyramidal damage has increased muscle tone, tremors, speech disorders, abnormal gait, and so on. If accidentally contact with the skin during use, remove contaminated clothing and rinse with running water; if accidentally contact with eyes, lift the eyelids immediately or flush with running water or normal saline. If inhaled, quickly leave the site to fresh air to keep the airway unobstructed. If breathing is difficult, oxygen should be delivered in time. If breathing stops, take artificial respiration immediately and seek medical treatment promptly. If careless eating occurs, drink enough warm water for vomiting and seek medical treatment promptly.
