ELECTRICAL PROPERTIES OF CADMIUM-ZINC-PHOSPHATE GLASSES AT HIGHER ELECTRIC FIELDS.

The cadmium-zinc-phosphate glasses previously described by the authors are further examined in relation to their electrical conduction properties at higher applied fields above 2. 5 multiplied by 10**4 V cm** minus **1 at room temperature. Following the assumptions of Lacharme and Isard, the mechanism of electrical conduction seems to be due to the Poole-Frenkel effect in these particular glasses. The values of relative dielectric constants evaluated from the slopes of log I versus V** one-half curves are close to the static dielectric constants.
