      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.
