Abstract
Codeposition of antimony and tin from acidic chloride and chloride-sulfate baths was investigated. The calculations of
distribution of species showed domination of neutral SnCl2 and anionic SbCl4
– complexes in chloride solution, while in the presence
of sulfate ions neutral SnSO4 and cationic SbCl2+ complexes were found. Cyclic voltammetry, anodic stripping analysis and
potentiostatic measurements showed that antimony deposited favorably and the reaction run under limiting control. Analysis of
chronoamperometric curves suggested instantaneous nucleation of the solid phase in the chloride bath, but progressive model was
more probable in the presence of sulfate ions.
