Influence of dislocation density of copper electrode on the kinetics of anode process in acidic CuSO4 solution
Deformed copper samples were burned at different temperatures. This procedure formed different dislocation density in the samples. Then such prepared samples were used as the anodes in acidic C11SO4 solution. The voltage for electrolyse was 10 mV. The experiment has shown that the increase of the di...

| Summary: | Deformed copper samples were burned at different temperatures. This procedure formed different dislocation density in the samples. Then such prepared samples were used as the anodes in acidic C11SO4 solution. The voltage for electrolyse was 10 mV. The experiment has shown that the increase of the dislocation density in the anode leads to the increase of the density of anode current. It was discovered that the density of anode current could become 2,5 times bigger. This can be explained by the fact that dislocations decrease the potential barrier during the transfer of copper ions from the grid into the electrolyte. |
