通过电化学方法研究了浇铸的新型Pb-0.6％Sn-0.6％Sb阳极和工业用的Pb-0.06％ Ca-0.6％Sn阳极在CuSO4-H2SO4体系下的电化学性能,结果表明新型的Pb-0.6％ Sn-0.6％ Sb阳极电催化性能和耐蚀性能均比Pb-0.06％Ca-0.6％Sn阳极优异.采用扫描电子显微镜观察了两种合金材料极化24h后的表面形貌,图像显示Pb-0.6％ Sn-0.6％ Sb合金阳极表面形貌更为均匀和致密.X-射线衍射图显示,对应PbO的衍射峰Pb-0.6％ Sn-0.6％ Sb阳极材料比Pb-0.06％ Ca-0.6％ Sn阳极材料的弱,但PbO2的衍射峰Pb-0.6％Sn-0.6％Sb阳极材料比Pb-0.06％Ca-0.6％Sn阳极材料的强,说明Pb-0.6％Sn-0.6％Sb阳极的导电性比Pb-0.06％Ca-0.6％Sn阳极要好,电沉积铜的对比实验表明,Pb-0.6％ Sn-0.6％ Sb合金材料的槽电压比Pb-0.06％Ca-0.6％ Sn合金材料要低,电流效率有所提高,同时阴极铜和电解液中铅含量也较小.
