Electrode for electrolysis, anode for ozone electrolysis generation, anode for persulfate electrolysis generation and anode for chrome electrolytic oxidation

摘要

Settlement topic It possesses the high oxygen overvoltage which is used for the electrolytic oxidation reaction and it designates that the electrode for the electrolysis of long-lived is offered as purpose. SolutionsIt possesses the electrode surface of valve metallic oxide, the base substance of said electrode surface excludes the valve metal and the precious metal (the silver (Ag). The below same.)Being the electrode for electrolysis which consists of the alloy, crystal of the valve metal of the said electrode surface adjacent area has long and narrow the crystal grain, the precious metal inside the range of vertical depth direction 10 millimicron 5 atmoic % is below from the electrode surface, at the same time, the electrode for electrolysis which features that the valve metal of the surface in the electrode surface adjacent area has the oxide film. Choice figure It is not
