Abstract

The influence of the phase and chemical compositions of two aluminum silicate minerals – bentonite and kaolinite – on the solid-phase conversion of depleted uranium tetrafluoride into U
₃O
₈ was investigated. It is shown that after their preliminary preparation by heat treatment or mechanical activation aluminum silicates can be used as reagents alternative to silica.
