Description

The local structures around Zr atoms such as coordination number of oxygen and cations, and the Zr-O and Zr-Ln (Ln; La, Ce)interatomic distances in the (La1-XCeX)2Zr2O7 pyrochlore compounds (X = 0--0.25), where Ce is a simulation of actinides, were studied by means of extended X-ray absorption fine structure (EXAFS) spectrometry. The local structure determined by EXAFS in this study is discussed in relation to the dissolution behavior of (La1-XCeX)2Zr2O7 (leaching rates of Zr, La and Ce) in an acid solution (pH = 1) at 363K reported previously. The difference in the local structure before and after leaching test was also investigated
