Abstract:The influence of additive and technological parameter on cathode process of electrodepositing Pb in PbSiF6-H2SiF6electrolytic system was investigated by motional electric potential. The electrochemical mechanism of the process is indicated. The experimental results showed that controlling Pb in electrolyte as 40~120 g/L,H2SiF6as 90~120 g/L, sodium wood-sulfonate additive as 4 gL, high quality deposit Pb was obtained.
