Planetary ball milling was investigated as a method of comminuting presintered thoria (ThO/sub 2/)-urania (U/sup E/O/sub 2/) granules for the preparation of sinterable feed powders. The experimental results indicated that planetary ball milling offers significant size-reduction rate advantage over conventional wet ball milling.

Three types of graphene sheets (GS) were decorated by chemical oxidation, electrolysis and ball-milling, respectively. These oxidized samples were characterized using SEM, XRD, Raman, FT-IR and XPS, and then were employed to enrich U(VI) from aqueous solutions as a function of pH, contact time and initial concentration of U(VI). These results displayed that the quantities and types of oxygen

Uranium sesquisilicide (U 3 Si 2) has been prepared by high energy ball milling of the elemental powders. Starting materials were combined in a planetary ball mill and milled with a 10:1 ball-to-powder charge for varying times between 0 and 24 h. Temperature and pressure of the milling vial were monitored to gain insight into reaction kinetics.
