An ultrasonic attenuation study of hydronium-β″ -alumina

Abstract

The ultrasonic longitudinal wave attenuation peak caaused by the hydronium ions in H3O+-β″ -alumina has been generated. The peak gives 0.15 eV as the activation energy for H3O+ motion and 0.8 GHz as the ion hopping rate at room temperature. This rate can be used to determine the optimum frequency for ultrasonically aiding the field-assisted ion-exchange process involved in electrolyte synthesis.
