Batteries : Manganese oxide, especially manganese(IV) oxide (MnO), is widely used as a cathode in alkaline batteries and lithium-ion batteries, due to its good electrical properties.
Catalysts : Used as a catalyst in chemical reactions, including wastewater treatment and in the petroleum industry for catalytic cracking.
Raw material in steel manufacturing : Added in steel manufacturing to improve its mechanical properties and corrosion resistance.
Chemical synthesis : Used in the synthesis of certain chemical compounds and in the manufacture of lubricants.
Construction: used as a pigment in ceramics and concrete coloring for its colors ranging from brown to black. It can be used in the manufacture of insulation.
Other uses: It can also be used in the manufacture of certain specialized glasses, such as those resistant to radiation.
