Abstract
It is shown theoretically that the milling of complex metal oxides is not a fundamental limit of dispersion, if provided with the necessary energy loading of the mill and taken to passivate the surface free energy of Gibbs. The transition to the production of ultrafine (0.1-1 mm) and nano (10-100 nm) oxide is achieved when most energy loading of 2000-4000 W / g. It is suggested that the power density of a planetary mill has a power (cubic) dependence on the size of the free volume of the reactor. The reported study was partially funded by RFBR according to the research project No. 15-42-00106.
