Manganese oxide is often used as a catch-all term for the oxides of manganese. Manganese dioxide is an inorganic compound that has the formula MnO 2 and is the primary component by far of pyrolusite, itself the major ore of manganese. This blackish or brown solid material occurs naturally and is extensively mined for its colouring properties

From Wikipedia. Manganese(IV) oxide 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 and a component of manganese nodules. The principal use for MnO2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery.MnO2 is also used as a pigment and as a precursor to

Manganese dioxide is a very common material in the battery field, which has been used for a long time as the positive electrode active material in zinc–carbon dry cells and alkaline manganese dioxide cells. It was also regarded as one of the most promising positive electrode materials for lithium cells, because it was a strong oxidant and

Manganese dioxide is used in drying black paints and in the preparation of oxygen and chlorine. It also acts as a catalyst in the production of artificial flavors like vanilla and as an oxidizing agent in treating uranium ore to produce the oxide-concentrate. Manganese compounds have also been used in the coloring of ceramics and glass
