Application
Manganese(III) oxide is utilized primarily for its role in producing ceramic magnets and semiconductors, owing to its unique properties. Beyond these applications, it serves as a precursor to lithium manganese oxide, which is an important material in battery technology, particularly as a useful cathode component. This noncombustible, black and lustrous compound, sourced from either igniting manganese(IV) oxide or a manganese(II) salt in air, also occurs naturally in the mineral forms braunite and manganite. Its structure, comprising Mn3+ and O2- ions, allows it to react slowly with cold dilute acids and undergoes disproportionation with concentrated alkalis, further underscoring its utility across various industrial applications.
