The electrode plays a significant role in the electrolytic industry. The application of the electrode material is very extensive on the electrochemical industry and electrometallurgical industry, seeking the appropriate electrode material also therefore appears extremely important.A comprehensive description of recent research on the electrode material including its function, application, developing process, the advantage and disadvantage of the common electrode material in the electrolytic industry. Specially the development of titanium base and other substrate coating electrodes was summarized. On the basis of summarizing the development, according to the electrolytic industrial requisition for electrode material, Al/(SnO₂ +Sb₂O₃)/ PbO₂ and Al/(SnO₂ +Sb₂O₃ +MnO₂)/PbO₂ anodes were prepared by the thermodecomposition, the chemical deposition and the electrodeposition. It was proved to be possible for preparing the anode by the theory.Through the orthogonal experiment, the main factors which affecting the composes and outward appearance of the intermediate layer are showed as follows: the fluid ingredient.the strata times,the thermodecomposition temperature. The optimum conditions of preparation : the strata times is 10, the thermodecomposition temperature is 450℃ and 500 ℃, the fluid ingredient (spread fluid 1: SbCl₄ 3.2g, SnCl₄-5H₂O 21g; Spreads fluid 2: SbCl₃3.2g, SnCl₄5H₂O 21g, 50%Mn (NO₃)₂ solutions 10ml). Through the orthogonal experiment, the main factors which affecting the binding force, smoothness, the superficial appearance of the electrode are showed as follows: the ingredient of chemical plating fluid, the ingredient of coating fluid, the times, the temperature of thermodecomposition.The optimum conditions of preparation : the oxidant (NH4) ₂S₂O₄ is 0.5 0.7mol/L.The chemical composition and element distributed situation of the coating was studied by means of the EPMA-1600 electron probe.The research indicated, the main chemical composition of the coating which doesn't contain the manganese is Sn, O, Sb ,in accounts for 45.6 49.4%, 33.5 - 34.2%, 5.6 8.7%. the main chemical composition of the coating which contains the manganese is Mn, O, Sn, Sb which is in accounts for 38.8 53.2%, 26.1 - 28.3%, 14.7- 15.7%, 6.1 13.5%. The principalconstituent of the coating is Pb and O and a few of Sn> SIk Mn after deposited chemically PbO2. The principal constituent of the coating still was Pb and O and a few of Sn^ SK Mn after electrodeposited PbO2. The coating which the fluid content few SnCLt appears the quite serious crack and the hole. The coating which the fluid content much SnCLt is compact, quite smooth.without crack at 450 °C and 500 °C .Chemistry coating surface is quite smooth, compact, with small crystal grain .The PbC>2 coating prepared by the electrodeposition is with thick crystal grain which appears the octahedron shape.The structure of the coating and the electrode was studied by means of the D8 Advance X- ray diffraction meter made from the German. The result indicated that, the coating is the crystalline state composed of the tin, the stibium, the manganese oxide compound or two kind of compound, the PbC>2 coating prepared by the electrodeposition is P -PbC>2 and a -PbC>2 whose diffraction peaks are quite.Al/(SnO2+Sb2O3)/PbO2 and Al/(SnO2+Sb2O3+MnO2)/PbO2 anode material are applied in the zinc electrolysis. The tank voltage of Al/(SnO2+Sb2O3)/ PbO2 anode is 3.3V, the current efficiency is 87% in the pure ZnSCVI^SCU watery solution system. The tank voltage of Al/(Sn02+Sb203+Mn02)/Pb02 anode is 3.2V, the current efficiency is 86.5%. 87% in the pure ZnSO4-H2SO4 watery solution system. The lifetim of the optimum sample is longer than 18h.Through the above research, It is concluded that the related conclusion on the preparing anode material, and proposed some further develop direction.
