Abstract
Thorium is most commonly precipitated as oxalate, because of the high efficiency regardless of precipitation
conditions. Thorium oxalate readily decomposes into fine-grained ThO2 during heating, but
keeps the macrostructure of the oxalate platelets. To assess the effects of precipitate macrostructure on
the sintering behavior, different platelet morphologies were prepared and sintered. There are two factors
which influence the sintering: the presence of holes within the platelets and the size of the platelets.
Small platelets or precipitates with holes generally sinter to thorium dioxide pellets of a higher density
and smaller grain size.
