Abstract

X-ray and Raman measurements show that beta -BaZr2F10 becomes disordered at pressures greater than 3.7 GPa at ambient temperature. This transformation occurs via a largely displacive mechanism because the disordering is reversible. Comparisons of glassy BaZr2F10 and the high-pressure states of beta -BaZr2F10 provide structural insight into the medium-range order of ionic glasses. Specifically the authors believe that layers of tightly packed pentagonal bipyramidal units are present in the glass.
