Abstract

Brillouin spectroscopy has been used to measure the compressional and shear sound velocities of vitreous boron oxide (B2O3) under nonhydrostatic and quasi-hydrostatic conditions up to 18·8 and 13·5 GPa, respectively. Our experiments confirmed a pronounced velocity-pressure hysteresis and careful preparation of an anhydrous sample showed that this hysteresis was not due to the presence of water in B 2O3. Further, upon decreasing pressure our results are consistent with a discontinuous drop in the compressional and shear velocity near 3 GPa. We believe that this discontinuity may be the result of a structural transition between two vitreous polymorphs.
