Zusammenfassung:	Process for making a nanoparticulate manganese oxide of the formula MnxOy with x being integers in the range of from 1 to 3 and y being integers in the range of from 2 to 4, and x < y, said process comprising the following steps:(a) melting manganese metal under a non-oxidizing atmosphere,(b) withdrawing a vapor over the molten manganese, said vapor comprising manganese in gaseous form and the gas from the non-oxidizing atmosphere,(c) mixing the vapor withdrawn in step (b) with an oxidizing gas selected from oxygen-depleted air with at least 5 % by volume of oxygen, air, oxygen and oxygen-enriched air, thereby forming an oxide of manganese,(d) cooling the gas containing said oxide of manganese.
