✦ Synopsis

Commercially available silicate-based glasses, which have been used for high quality glassware, glass fibre and so on for decades, are rather complicated in composition and therefore an understanding of their structural characteristics in comparison with those of simpler glasses such as alkali and alkaline earth silicates [1-4] has been investigated in only a few works [5][6][7]. From the standpoint of immobilization of high-level radioactive waste, borosilicate glasses and Synroc ceramic materials have been regarded as the best candidates [8][9][10]. This is due to the fact that multicomponent glasses have the capability to form free spaces with different sizes among their constituent atoms, into which foreign atoms, that is radioactive atoms, can be incorporated. The silicate-
