LOCAL ENVIRONMENT OF Zr IN BARYUM FLUOROZIRCONATE GLASSES : THE EXAFS POINT OF VIEW

摘要

EXAFS studies (coordination number, mean M-F distance) for Zr4+ ions in vitreous phases of BaF2 -ZrF4 system lead to a coordination number between 7 and 8. Numerous crystallized compounds involving the various C.N. known in crystal chemistry of zirconium fluorides were used as references.
