Abstract

The investigation of the oxyfluorides is of great interest since the fluorine for oxygen substitution leads very often to dramatic changes of the physical properties of the resulting materials. This is especially true for those properties characterizing short range order in the structures involved. This type of substitution has been studied recently in various structural types : rutile, perovskite, spinel, garnet, fluorite, etc ... The sharp evolution of physical properties which parallels the increase in the fluorine substitution rate allows a better understanding of the mechanism of the solid state reactions between fluorides and isostructural oxides.
