biostudies-literatureUnknown10Kiefer CThe impact of temperature on a freshly precipitated ThO<sub>2</sub>(am, hyd) solid phase was investigated using a combination of undersaturation solubility experiments and a multi-method approach for the characterization of the solid phase. XRD and EXAFS confirm that ageing of ThO<sub>2</sub>(am, hyd) at <i>T</i> = 80°C promotes a significant increase of the particle size and crystallinity. TG-DTA and XPS support that the ageing process is accompanied by an important decrease in the number of hydration waters/hydroxide groups in the original amorphous Th(IV) hydrous oxide. However, while clear differences between the structure of freshly precipitated ThO<sub>2</sub>(am, hyd) and aged samples were observed, the characterization methods used in this work are unable to resolve clear differencFrontiers in chemistry1042709https://www.ebi.ac.uk/biostudies/studies/S-EPMC9705364biostudies-literatureInterlink between solubility, structure, surface and thermodynamics in the ThO<sub>2</sub>(s, hyd)-H<sub>2</sub>O(l) system.PMC9705364Gaona XGeckeis HSchild DRothe JKiefer CVitova TAltmaier MDardenne KCevirim-Papaioannou NNeill TfalseInterlink between solubility, structure, surface and thermodynamics in the ThO<sub>2</sub>(s, hyd)-H<sub>2</sub>O(l) system.The impact of temperature on a freshly precipitated ThO<sub>2</sub>(am, hyd) solid phase was investigated using a combination of undersaturation solubility experiments and a multi-method approach for the characterization of the solid phase.
