Manganese dioxide Wikipedia

Manganese dioxide is the inorganic compound with the formula MnO 2.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 MnO 2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery. MnO 2 is also used as a pigment and as a precursor to other manganese
