Raman spectrum of pressure compacted fused silica

Abstract

Raman spectra of compacted fused silica are presented. Fused silica was sujected to a pressure of 9.0 GPa for 1 hr at 23 °C. The density of the compacted silica was 2.40 g cm−3 compared to 2.22 g cm−3 for the uncompacted glass. Various interesting features of the spectrum are discussed. (AIP)
