Keywords:vitrification, borosilicate glass, raman spectrum, silica structure

To understand the structural property of borosilicate glass frit for vitrification of radioactive wastes, we prepared the glass frit samples which coordinated alkaline component and B2O3 amount and measured the Si-O bridge structure of those samples by using Raman spectrometer. Moreover, we made the simulated waste glass samples which added non-radioactive nitrate solution to those frit and observed a change of Raman spectra by glass composition.
