Abstract

A-site substituted cerium metavanadates, Ce1-xSrxVO3, were synthesised by solid-state reactions from single-phase powders of the corresponding orthovanadates. All samples were found to exhibit an orthorhombic perovskite structure of space group Pnma (62) with a = 5.5181 (3), b = 7.7853 (2) and c = 5.5155 (4) angstrom for Ce0.85Sr0.15VO3. Conductivity measurements were performed in air and in dry 5% H-2-Ar with conductivity values at 700 degrees C ranging from 0.1 to 2.5 S cm(-1) with peaking at 6 S cm(-1) in reduced atmosphere. X-Ray diffraction patterns and thermal analyses have shown that the reduction of Sr-doped CeVO3 from the equivalent orthovanadate is redox phase reversible without formation of parasitic phases while the undoped CeVO4 is not.
