Manganese(IV) oxide is used as a pigment and as a reagent inorganic synthesis especially for the oxidation of allylic alcohols. It is also used for dry -cell batteries such as the alkaline battery and the zinc-carbon battery. It is involved in the preparation of other manganese compounds. It is a precursor to ferromanganese and related alloys, which is useful in the steel industry. It catalyses the decomposition of hydrogen peroxide into oxygen and water. Further, it is used to prepare manganese(II) sulfate, manganese(II) chloride and potassium permanganate. In addition to this, it is used in ceramics and glass manufacturing as an inorganic pigment.
