Manganese dioxide Wikipedia

Manganese(IV) oxide 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 drycell batteries, such as the alkaline battery and the zinccarbon battery. MnO 2 is also used as a pigment and as a precursor to other manganese

The latter process, involving the reduction of manganese oxides by carbon, is actually a complex thermodynamic problem. The higher oxides (MnO 2, Mn 2 O 3, and Mn 3 O 4 ) can all be reduced to manganous oxide (MnO) by carbon monoxide, but this lower oxide can be reduced to the metal only at elevated temperatures by carbon.
