DIELECTRIC RELAXATION IN Cs₂O-SiO₂ AND Na₂O-SiO₂ GLASSES.

Dielectric loss curves have been determined for a number of Cs//2O-SiO//2 and Na//2O-SiO//2 glasses. The forms of these curves, as well as those of the distributions of relaxation times derived therefrom, are similar for all glasses studied. The G( tau )- tau curves are all asymmetric to the small tau side, and may be super-imposed by shifting along the relaxation time axis. It is suggested that the observed distributions of relaxation times may not reflect corresponding distributions of molecular processes. 17 refs.
