Abstract

Materials of composition CaZrTi2j2xNbxFexO7 with the fluorite-related zirconolite structure have been prepared. The 57Fe Mo¨ ssbauer spectra show that iron is initially located in the five co-ordinate cation sites. As the iron content increases the iron enters the octahedral sites until, at a composition CaZrTi0.4Nb0.8 Fe0.8O7, ca. 50% of the iron is five co-ordinate and the remainder is located in the octahedral sites.
