SOLID-PHASE INTERACTION OF URANIUM TETRAFLUORIDE WITH ALUMINUM SILICATES

摘要

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 U3O8 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.
