【摘要】 用循环伏安法与计时电位法研究了950℃下碱性冰晶石熔体(分子比6.5)中铝在钨电极上的电化学沉积过程。结果表明,由于铝与钨形成金属间化合物,导致铝沉积过程的复杂化,因而不能简单地把钨作为研究冰晶石熔体中铝析出与溶解的工作电极。更多还原

【Abstract】 The electrochemical deposition of aluminium on tungsten electrodes has been studied by using the technology of cyclic voltammetry and chronopo tentiometry in basic cryolite melts (CR=6.5) at 950℃. It is found that formation of intermetallic compounds of aluminium with tungsten complica tes aluminium electrodeposition process. Hence it is not appropriate that tungsten is simply used as working electrode in the study of aluminium dep osition and dissolution in cryolite melts.更多还原
