Abstract
ABSTRACTWe have found that lanthanum zirconate (La2Zr2O7) with a pyrochlore structure can be used as a superior host phase for actinide and lantanide elements contained in high-level nuclear waste. The solubility of Ce, Nd and Sr in La2Zr2O7 is determined because Ce and Nd may simulate the segregation of actinide and lanthanide elements at the grain boundaries of polycrystalline La2Zr2O7. The results show that La2Zr2O7 is a promising material for confining actinide and lanthanide elements in its crystal structure.
