铅锑电极上PbO_2生长过程的研究

Studies on the Growth Process of PbO_2 on the Lead-Antimony Electrodes

应用电位阶跃和阻抗跟踪法，考虑基底铅氧化电流的影响，研究了铅锑电极上ＰｂＯ_２的生长过程，探讨了锑对这一过程的影响．铅锑电极上ＰｂＯ_２生长过程符合二维瞬时成核和生长过程机理，锑将抑制这一过程的进行。

The potential-step and impedance tracing methods were used to study the growth process of PbO_2 on lead-antimony electrodes with the oxidation current of lead substrate being considered.The influence of antimony on the growth process was investigated.The growth process of PbO_2 on the lead-antimony electrodes obeys the rule of two dimentional instantaneous nucleation and growth process and the antimony will retard this process.
