Abstract
Mechanochemical impact induces oxidation of U(IV)O2 in presence of alkali metal peroxides Li2O2 and Na2O2 during liquid-assisted grinding, resulting in respective alkali U(VI) triperoxide phases (e.g. Na4[UO2(O2)3]·9H2O), based on powder X-ray diffraction analysis, solid- and solution-phase vibrational spectroscopy.
