“…1 and 2, S glass has a three-dimensionally higher polymerized network structure, whereas 20N80S glass has many O nb ions and a less polymerized network structure. The simulated Young's moduli for S and 20N80S glasses, which have values close to the experimentally measured values of 72 and 57 GPa [32], respectively, suggest that S glass has a higher average network strength than 20N80S glass. On the other hand, the void sizes and distributions vary widely for both glasses (Fig.…”

“…The measured TPB failure strains at 77 K for silica fibers are about 18% [12]. Recently, using TPB, failure strains as high as 23.5% are reported for sodium silicate glass fibers [13], 21% for sodium alumino-silicate fibers [14], and 13% for E-glass fibers [15]. These high failure strain values also correspond to intrinsic failure for the same reasons mentioned earlier for failure strengths in pure tension.…”

We present the first direct observation of high-coordinated Si and Al occurring together in a series of high-pressure sodium aluminosilicate glasses, quenched from melts at 6 GPa. Using 29Si MAS NMR, we observe that a small amount of Al does not have a significant effect on the amount of V Si or VI Si generated, but that larger Al concentrations lead to a gradual decrease in both these species. Na isotropic chemical shifts indicate decreases in the mean Na-O bond lengths with increasing pressure, which are more dramatic at higher Al contents. Recovered glass densities are about 10 to 15% greater than those of similar ambient pressure samples. However, the density increases due to the combined coordination changes of Al and Si are estimated to total only about 1 to 2%, and are roughly constant with composition despite the large effects of Al content on the individual coordinations of the two cations. Thus, effects of other structural changes must be significant to the overall densification. Apparent equilibrium constants for reactions involving the generation of high-coordinated species show systematic behavior, which suggests an internal consistency to the observed Si and Al coordination number shifts.
