> The effects of additives such as NH 2OH·H 2O, sucrose, calcium gluconate on the qualities of cuprous oxide and the action mechanism in the process of electrolysis were studied. The results suggested that NH 2OH·H 2O and sucrose can inhibit the deposition of CuO, but can not inhibit the deposition of copper in the electrolysis process. Calcium gluconate can not only effectively prevent......

电解电压对阳极氧化铝膜微观形貌的影响王晓燕1,翟秀静1,张廷安1,符岩1,郑双2(1.辽宁省沈阳市东北大学2.沈阳航空工业学院,沈阳 110032)摘 要:以H2SO4为电解液对高纯铝箔进行阳极氧化,考察电解电压对多孔阳极氧化铝膜微观形貌的影响.结果表明,在一定范围内氧化铝膜纳米孔孔径随电解电压增加而增大,但过高的电压值将导致铝箔的快速击穿.1.0mol/L H2SO4为电解液采用20V电解电压制得的氧化铝膜最好.电解液硫酸浓度过高使得纳米孔局部连通现象增多.关键词:金属材料； 阳极氧化铝膜； H......
高纯铁制备技术综述 张力1,徐志高1,罗远辉1,孙辉1,王力军1 (1.北京有色金属研究总院,北京,100088) 摘要:本文介绍了溶剂萃取,离子交换,电解精炼和区域熔炼等冶金提纯方法在高纯铁制备过程中的应用.采用溶剂萃取法和离子交换法,可以除去溶液中的大多数金属杂质,得到纯度为4N的高纯铁溶液.通过氢还原或电解精炼,可进一步去除杂质元素并获得纯度为6N的金属铁材料.区域熔炼法可对铁进行进一步精炼,使纯度达到极限.对不同的原料纯度以及不同的产品纯度要求,采用的工艺方法也有相应的变化,但一般采用几种方法相结合的工艺路线制备品质优良的高纯铁. 关键词:高纯铁; 溶剂萃取; 离子交换; 电解精炼; 区域熔炼; high purity iron; solvent extraction; ion exchange; electrolysis refining,zone melting......
