英文摘要	When incorporating actinides into zirconolite for high-level radioactive waste immobilization, Al3+ and Fe3+ ions generally act as charge compensators. In this study, we rationally designed a series of Ca1-xLnxZrTi2-xmml:mfenced close=")" open="("separators=Al,FexO7 (Ln = La, Nd, Gd, Ho, Yb) to unravel the dopant solubility and evolutions of the crystalline phase and local environment of cations through synchrotron X-ray methods. It was found that single zirconolite phase is difficult to obtain and the fraction of perovskite have an increase with x from 0.1 to 0.9 in Ca1-xLaxZrTi2-xAl,FexO7. For the local environment of Zr4+, the major form is ZrO7 with a trace of ZrO8.
