Based on the discussion of the previous section, we would also expect that structural complexity and disorder present in glasses would tend to decrease the thermal conductivity. This is true, especially when alkalis are added to sodium silicate glasses. Figure 4.32 shows the effect of replacing SiOa in Na20-Si02 glass with other oxides.

It is furthermore interesting to note that in a specific refraction -composition diagram (Fig. 71) for the potassium- and sodium-silicate glasses studied, the points are... 

Based on the characteristic shape of edge components in the EPR spectra of products formed by the mechanical treatment, UV irradiation (see Figure 7.31), or y-irradiation of nitrogen-doped vitreous silica, these components were assigned to =Si-N -Si= radicals. Mackey et al. [106] recorded an individual EPR spectrum of =Si-N -Si= radicals in sodium silicate glass.
