The synthesis, characterization and bulk thermal expansion studies of a series of compounds with the general composition Th1-xNd xO2-x/2 (0 ≤ x ≤ 1) are reported. The XRD pattern of each product was refined to know the solid solubility limit and the homogeneity range. The solid solubility limit of NdO1.5 in ThO 2 lattice, under the conditions of slow cooling from 1673 K, is represented as Th0.50Nd0.05O1.75 (i.e., 50 mol.% of NdO1.5). The subsequent compositions were found to be bi-phasic as Nd2O3 peaks started appearing. The bulk thermal expansion measurements from 293 to 1123 K, as investigated by a dilatometer, revealed that the α1 value, within the homogeneity range, increases with increasing Nd3+ content. © 2004 Elsevier B.V.
