摘要：
A detalied electron, and X-ray powder, diffraction study has been made of the cubic, fluorite-related solid solution fields in a range of ZrO2Ln2O3 systems. A rich variety of composition-dependent diffraction effects were observed, leading to the realization that it is possible for there to be a much more gradual transition between apparently distinct structural types as a function of composition than was previously thought to be the case. Labels such as F-type (or C1), C-type (or C2) or pyrochlore as traditionally used are rather inappropriate and unhelpful when attempting to describe structural variations across and between such solid solution fields. © 1991.
