The phase relationship between PuO 2-x and CaTiO 3 at room temperature was investigated by X-ray diffraction. It was found that Pu was soluble to at least 20 mol% in CaTiO 3 in Ar-8% H 2 . Solubility of Pu in CaTiO 3 was extremely limited (below 5 mo

The EXAFS (extended X-ray absorption fine structure) analyses were carried out for Ti–K, Ce–L3, Nd–L3 and U–L3 edges to make clear the local structures in (Ca 1− x Ce x )TiO 3 ( x =0.10, 0.20), (Ca 1− x Nd x )TiO 3 ( x =0.05, 0.10, 0.15,

The two phase transitions of CaTiO3 and (Ca0.85Nd0.15)TiO3 were studied by high temperature X-ray diffraction and differential thermal analysis in the temperature range 300–1723 K. The presence of the two kinds of phase transitions in CaTiO3 and (C

The solubility limits of Ce, Nd and U in CaTi0 3 , one of the promising host matrix for fixation of lanthanide and actinide elements, were determined by X-ray diffraction to be between 20 and 30 mol%, between 20 and 30 mol% and between 0 and 3 mol%,

Heat capacity measurements were carried out on (Ca0.85Nd0.15)Ti03 and (Ca0.80Nd0.20)Ti03 in the temperature range of 298–550 K by using a direct heating pulse calorimeter and a differential scanning calorimeter. The results indicate the presence of
