Manganese Dioxide Micron Powder
Manganese dioxide is the inorganic compound with the formula MnO2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese. Manganese dioxides have attracted great attention because of their excellent physicochemical properties, rich structural variety, low cost and environmental friendliness. There are various polymorphic forms of manganese dioxides including alpha (¡), beta (¢), delta (¤) and gamma (£) due to the different linkways of the primary unit [MnO6] octahedra. They find place in extensive potential applications such as electrochemical energy storage and conversion, catalysis, ion exchange and molecular adsorption. MnO2 is used as a colorant and decolorizer in glass, white ware, enamels and pottery. It is also used in battery cathode mixes and electronics. There is promising potential to use MnO2 in solid state lithium-ion batteries for automobiles. In addition, MnO2 is used in ferromagnetic ferrites and as a catalyst.
