Application

Manganese dioxide is mainly used as a depolarizing agent in dry batteries. It is a good decolorizer in the glass industry, which can oxidize low valent iron salts into high valent iron salts, turning the blue-green color of glass into a weak yellow color. Used in the electronics industry to produce manganese zinc ferrite magnetic materials.
