摘　　要：采用循环伏安法、恒电位阶跃法和SEM技术研究了H2SO4-NH4F-SbF3体系中锑的电结晶机理。结果表明,锑电化学成核机理与电位有关,其电结晶按照包含成核阶段的螺旋位错生长机理进行。Electrocrystallization of antimony from H2SO4-NH4F-SbF3 electrolyte system were investigated by means of cyclic voltammetric,chronoamperometric and SEM technique.The results show that the electro nucleation mechanism of antimony is dependent on potential,and the electrocrystallization of antimony follows the spiral growth mechanism,and undergoes nucleation process.
