【摘要】 高锑引起焊锡电解中阳极钝化是一个难题 ,引起钝化的主要原因是合金表面存在较多SbSn化合物 ,由于该化合物标准电极电位较铅、锡的标准电极电位正 ,故不发生电化溶解而以网状致密的结构留在阳极表面的阳极泥中 ,导致阳极钝化更多还原

【Abstract】 Passivation caused by SbSn in electrolysis of solder containing antimony is studied Compound,SbSn,covers the surface of anodes,and its potential is higher than both lead and tin, respectively The layer of this compound protects the lead and tin from dissolving in electrolyte, and is not able to dissolve itself, that is the reason for anode passivation更多还原
