N2 - In the course of investigating the mechanism of conductivity of fast-conducting, multicomponent lithium fluoroborate-type glasses, an isothermal drift in the conductivities has been found at temperatures so far below the normal glass transition (∼ 300°) that an origin in normal glass annealing effects appears improbable. Analysis of the 1st order kinetics of this relaxation in the temperature range 150-250°C yields an activation energy more than an order of magnitude less than that of the primary structural relaxation, suggesting the processunder observation is a secondary structural relaxation of the type frequently seen in polymer glasses.
