摘　　要：应用溶胶凝胶法制备不同焙烧温度的氧化物阳极涂层,SEM,EDX,XRD、强化电解寿命、循环伏安和电化学阻抗等测试表明,烧结温度对阳极涂层的表面形貌以及电化学性能有着很大的影响.随着烧结温度的升高,析氯电位相应增加,寿命相对较长,循环伏安电量与双电层电容值有所下降.The anode coatings of Ru-Ir-Sn oxide were prepared by sol-gel method with different annealed temperatures. The influences of annealed temperature in properties of anode coatings were characterized by scanning electron microscope （ SEM ） , energy dispersive X-ray detector （ EDX）, X-ray diffraction （XRD） , potential of chlorine evolution, accelerated life,cyclic vohammetry and electrochemical impedance spectroscopy （EIS） tests. The results showed that the annealed temperature affected the morphology of coatings, while the electric quantities of cyclic voltammetry and double layer capacitances of anode coatings had a tendency to fail down and the potential of chlorine evolution and accelerated life had a tendency to increase as the annealed temperature increased.
