Pb-0. 8%Ag-0. 1%Sn composite anode was prepared on the surface of aluminum substrate by the electrodeposition and applied to the zinc electrowinning. The electrochemical performance of the electrodeposition Pb-0.8%Ag-0.1%Sn composite anode was studied in zinc sulfate?sulfuric acid solution after a day polarization, which were compared with electrodeposition Pb-0.8%Ag anode and casting Pb-0.8%Ag anode. Meanwhile, the microstructure of three kinds anodes was observed by SEM and the phases were analyzed by X?ray diffractometry. The results indicated that the electrocatalytic activity and corrosion resistance of the electrodeposition Pb-0.8%Ag-0.1%Sn anode were better than those of other anodes. The X?ray diffraction indicated that the diffraction peaks of β?PbO2 ( 101 ) and PbOx ( 1
