The anodic polarization curves of PbO_2/Ti electrode in 10% diluted sea water,natural sea water,0.5N Na_2SO_4 and 5M NaCl solutions at 25℃ have been measured.The chloride and oxygen overvoltages of PbO_2/Ti electrode are lower than those of Pt/Ti electrode at high current density region. Corrosion rates at given current density are determined by the weight loss method during electrolysis in the above mentioned solutions.The results have shown that corrosion rates of PbO_2/Ti anode are greater than those of Pt/Ti anode,but they are far smaller than those of Pb-2%Ag anode. PbO_2/Ti electrode has been used successfully in cathodic protection sys- tem and in the reacting vessel for the production of sodium hypochlorite.
