What is Manganese(II,III) Oxide used for? Mn3O4 is sometimes used as a starting material in the production of soft ferrites e.g. manganese zinc ferrite, and lithium manganese oxide, used in lithium batteries. Manganese tetroxide can be used as a weighting agent while drilling reservoir sections in oil and gas wells. Manganese(III) Oxide is also used to produce ceramic magnets and semiconductors.
