What is Manganese Dioxide Powder? Manganese dioxide, an inorganic compound, has the chemical formula MnO2. Manganese dioxide is a amorphous black powder or black rhombohedral crystal; it is insoluble in water, weak acids, weak bases, nitric acid, and cold sulphuric acid and dissolves in concentrated hydrochloric acid under heating to produce chlorine gas. Manganese dioxide is a strong oxidizing agent in acidic media. Manganese dioxide (MnO2), known in nature as soft manganese ore, is the most abundant of all manganese compounds. The main ore of manganese dioxide is the soft manganese ore known to the ancients as a pigment.
Properties of Manganese Dioxide Powder Manganese dioxide is an octahedral structure; the oxygen atoms are on the top of the octahedral corners, the manganese atoms are in the octahedra, and the octahedra are connected by common ribs to form single or double chains; these chains and other chains are co-topped to form tunnel structure of gaps, the octahedra either become dense hexagonal piles, or become dense square piles. When manganese dioxide meets a reducing agent, it becomes oxidizing. If manganese dioxide is heated to 1400 K in a stream of hydrogen, manganese oxide is obtained; if manganese dioxide is heated in a stream of ammonia, brown-black manganese trioxide is obtained; if manganese dioxide is reacted with concentrated hydrochloric acid, manganese chloride, chlorine gas and water are obtained.
Applications of Manganese Dioxide Powder Manganese dioxide is one of the important components in batteries, both alkaline and zinc-carbon. Large quantities of this natural mineral are used every year in the manufacture of dry-cell batteries. Manganese dioxide powder is used as a depolarising agent in dry cell batteries, a catalyst and oxidizing agent in the synthetic industry, a coloring agent, decolorizing agent, and an iron removal agent in the glass and enamel industries. Manganese dioxide powder is used to manufacture manganese metal, special alloys, ferromanganese castings, gas masks and electronic materials such as ferrite. In addition, manganese dioxide powder can also be used in the rubber industry to increase rubber stickiness. MnO2 powder can also be used as a catalyst in chemical experiments. Manganese dioxide powder is used in the laboratory as a catalyst for the decomposition of hydrogen peroxide into oxygen; and as a catalyst for the decomposition of potassium chlorate into oxygen by heating. Manganese dioxide powder is used as an autocatalyst for potassium permanganate.
