Experimental and Theoretical Expression for the Molar Electrical Conductivity of Borosilicates

  • Rudol’f L. Myuller
Chapter

Abstract

The slight electrolytic dissociation, the comparatively high mobility of the dissociated ions, the unipolar conductivity, and the solid state —all these connect vitreous borosilicates, in an electrochemical context, with ionic crystals. Starting from this point, the author made a comparison between experimental results on the electrical conductivity of glasses and the values calculated from Frenkel’s theoretical formula [1]. It was clearly necessary to have a physical chemical justification for the application of this to amorphous, ionic-covalent glasses, since the formula had been derived for purely ionic crystalline solids. A regular lattice is absent in these glasses and they have, in addition to the conduction cations, immobile negatively ionized and nonionized atoms mutually interconnected by valence bonds in a three-dimensional network structure.
