Preparation of lead-sodium alloy by fused salt electrolysis using beta alumina

The electrolytic method of preparing lead-sodium alloy from the eutectic melt of NaCl-ZnCl2 at 623K using molten lead cathode and sodium ion conducting beta alumina solid electrolyte as diaphragm has been investigated. The characteristics of the alloy, like hardness, microstructure and its polarization behavior in battery grade 10N H2SO4 are studied and compared with that of pure lead
