Optimization of thorium oxalate precipitation conditions relative to derived oxide sinterability

A study on ThO2–LaO1.5 solid solution: synthesis, characterization and estimation of solubility of LaO1.5 in ThO2 at 1473 K

“…However, it is gratifying to note that without the addition of any binder and besides adopting relatively a low-temperature sintering procedure, we could achieve about 93% of theoretical density. This advantage derives from the enhanced homogeneity of the initial powder mix obtained from the coprecipitation technique [13].…”

Characterization of ThO2–UO2 pellets made by co-precipitation process

“…Atlas et al [23] prepared ThO 2 -20 wt%UO 2 pellets via coprecipitation of mixed oxalate from nitrate solutions by adding excess oxalic acid and studied various parameters which may affect the powder properties. White et al [28] investigated precipitation temperature, agitation and digestion time for the preparation of ThO 2 -25% UO 2 . Argo [29] prepared ThO 2 -20%UO 2 , ThO 2 -35%UO 2 and ThO 2 -50%UO 2 pellets (% in weight) by the co-precipitation method.…”

Synthesis and characterization of Th1−xLnxO2−x/2 mixed-oxides

“…Both monoclinic C2/m and C2/c type compounds appeared as thin square plates ( Fig. 2e and g, respectively) [73]. The microstructure of all the samples was always kept during the conversion of starting oxalates to final oxides (Figs.…”
