THE EFFECT OF ADDITIVES ON THE DENSIFICATION OF URANIA-THORIA COMPOSITIONS. Final Report-Metallurgy Program 9.2.2
An investigation is reported of the effect of several oxide additives on the densification of UO/sub 2/-ThO/sub 2/ compositions in which U/sub 3/O/sub 6/ is the initial uranium oxide. Also determined were the effects on densification of variation of the compaction pressure and of the pretreatment of the oxide powders. The validity of results was checked by two forming techniques, dry pressing and extrusion. The results are indicated as follows: additives had an increasing effect on densification with decreasing ThO/sub 2/ content; oxides of transition elements were most effective as additives for im i proving the densification; varying the forming pressure had little effect on densification; precalcination of the initial powders was effective in improving densification; and similar results as above can be achieved with extruded as well as dry-pressed specimens.
