Abstract:
High-dose gamma irradiation of electrodes provided with an active film consisting of 5 mol. % RuO2 and 95 mol. % TiO2 may produce electrodes whose chlorine overvoltage at 60°C in a solution containing 300 g NaCl per dm3 conforms to the relation for A 60Co source and doses about 4.9.105 C kg?1 (1.9 GR) were used. The gamma radiation has a positive effect of short duration in that it decreases the chlorine overvoltage, especially at higher cds. In the course of time the chlorine overvoltage of irradiated electrodes will increase beyond the values obtained with untreated electrodes.
