| Popis: | 1. The process of precipitation of dispersed bismuth on the cathode was investigated, and the optimum conditions for the formation of a fine powder were determined. The maximum powder current efficiency lies in the region of limiting current densities. 2. It was observed that precipitation of dispersed bismuth into the organic bath layer occurs at the potentials of SAA desorption from the cathode. The presence of cyclohexanone in the organic layer decreases cathode polarization. 3. To produce a fine bismuth powder, it is necessary to ensure a sufficient degree of cathode polarization, which may be achieved by adding polarizing agents to the electrolyte. |
