抄録

Structure analysis has been performed on permanently densified lithium silicate glasses by means of Raman scattering and ultraviolet (uv) reflection spectra. Higher energy shifts of Raman bands at around 450 and 580 cm^-1 and lower energy shift of first uv reflection band were found after densification. It is deduced that these shifts are due to the decrease of Si-O-Si bond angle and the increase of Si-O bond length. The decrease of the magnitude in densification and these band shifts with lithium concentration might be due to obstruction of the structural change by lithium ions.
