Abstract: Convective and diffusive processes result in the precipitation of iron sulfate films on iron electrode surfaces. This precipitate displays a peculiar morphology, characterized by an arragement of cells resembling those found in convection near a liquid-liquid phase boundary. Cell formation is assigned to electrolyte convection generated by nonuniformity of the sulfate film or associated with side wall effects. Freeze-dried iron sulfate deposits were observed by SEM. Patterns formed by arrays of squares or hexagons were obtained. © 1990 American Chemical Society.
