| 摘要 |
An electrode having a conductive platinum alloy coating and which has deteriorated in use in an electrolytic chlorate cell is heat treated at elevated temperatures of above 300 DEG C to regenerate the coating. The regeneration of the coating is exhibited by a decreased oxygen concentration in the cell off gases after the heat treatment. Further improvement in cell characteristics in severely deteriorated anodes may be achieved by coating the anode surface with a platinum group metal prior to or during the heat treatment.
