Issue Date: | 2002 | Publisher: | 1432-8488 | Journal: | Journal of Solid State Electrochemistry | Abstract: | The corrosion and passivation of Zn powder particles dispersed in a paste electrode immersed in 0.5 M Na2SO4 and 5x10(-3) M Na2HPO4 solutions were studied mainly by electrochemical impedance spectroscopy. The role played by diffusion in the mechanism of anodic oxidation of zinc powder particles has been shown. It was demonstrated that the anodic reaction of Zn powder in neutral or near neutral media involves at least two adsorbed intermediates. By simulating the porous structure of the electrode, some information about porous nature of zinc electrode could be extracted. | URI: | http://hdl.handle.net/10553/48957 | ISSN: | 1432-8488 | DOI: | 10.1007/s100080000192 | Source: | Journal of Solid State Electrochemistry[ISSN 1432-8488],v. 6, p. 119-125 |
