Abstract

Brillouin and Raman spectroscopy were performed on B2O 3 glass, which was compressed upto 57 GPa at 273 K, to study the existence of vitreous polymorphism in the vitreous B2O3. The sound velocities were found to increase smoothly upon decompression and also the boroxol ring Raman mode was found to disappear by 11 GPa. The basic reason for the the occurrence of polymorphism was found to be the change in the cation coordination from trigonal to tetrahedral. The results show that the transition between the polymorphs is steady while it is abrupt in the reverse direction.
