摘要/Abstract

摘要： 以工业废铁屑为原料制备高纯度电解铁 ,纯度可达 99.98%以上 .应用剩余电阻率比(RRRH)法 ,在外加垂直磁场 80 0 0e下分别测定该电解铁在 4 .2K和 2 98K时的电阻率 ,并得出样品对应的剩余电阻率比 (RRRH) .研究表明 :电解铁纯度越高 ,其RRRH 越大 .通过SEM断面形貌观察 ,在Ti基片上电解制备的纯铁非常致密

关键词: 纯铁, 电解制备, RRRH法, SEM

Abstract: The high purity electrolytic iron was made from scrap iron chips. The purity of electrolyzed pure iron was above 99.98% by chemical analysis. The resistivity was measured at 298 K and at 4.2 K under an applied longitudinal_magnetic field of 800 0 e. The ratio of resistivity at 298 K to that at 4.2 K, The value of residual resistivity ratio (RRR H) roughly depended on the purity of iron. Pure iron electrolyzed on Ti substrate had very compact texture as evident by SEM.

Key words: Pure Iron, Electrolytic preparation, RRR H method, SEM
