Quid est manganum (II, III) oxydatum adhibitum? Mn3O4 interdum adhibetur ut materia prima in productione ferritarum mollium, eg zinci ferrite manganese, et oxydatum lithium manganesum, in lithio gravida adhibitum. Manganese tetroxide uti potest ut gravis agentis dum exercendis sectiones in piscinis olei et putei gasi. Manganese (III) oxydatum etiam ad magnetes ceramicos et semiconductores producendos adhibitus est.
