Manganese dioxide
The chemical formula for this inorganic compound is MnO2. Manganese oxide is an amorphous black powder or orthorhombic black crystal.
Manganese dioxide, also known as amphoteric iron oxide, is a compound reaction in molten alkali system. A corresponding salt is available in the form a perovskite, such as BaMnO3 and SrMnO3 obtained by a reaction of compound in a liquid alkali system.
Manganese oxide is oxidized when it encounters a reductant. In order to get brown-black Manganese Trioxide, manganese dioxide is heated with ammonia in a steam.
It also becomes reducible when manganese oxide is in contact with strong oxidants. Mixing manganese dioxide with potassium carbonate or potassium nitrate and melting it will produce a dark green liquid. This liquid can be dissolved and cooled in water to form potassium manganate. It is an oxidant that can be very strong in acidic media.
Manganese oxide is used to produce metallic manganese as well as special alloys, gasmasks, electronic material ferrites, and ferromanganese casts. Manganese oxide can be used in rubber to increase viscosity. Manganese dioxide is also used as a chemical catalyst.
In the laboratory manganese dioxide is used to catalyze the decomposition of hydrogen peroxide to produce oxygen, as well as to catalyze decomposition of potassium chlorate to produce oxygen. Manganese dioxide is combined with elemental aluminum powder to form manganese and its oxide. Yellow glass, pigments and other uses.

Manganese Dioxide Properties:
Manganese dioxide is insoluble with water, weak acid and weak alkali. It also has a low solubility in nitric, cold sulfuric, or nitric acids. Manganese dioxide is dissolved in concentrated hydrochloric acids when heated. This produces chlorine gas.Manganese dioxide, also known as amphoteric iron oxide, is a compound reaction in molten alkali system.
