Electrocatalysis of carbon anode in aluminium electrolysisLAI Yanqing, LIU Yexiang, YANG Jianhong, and THONSTAD JomarDept. Metallurgical Science & Engineering, Central South University, Changsha... of the carbon anode in aluminum electrolysis is of the order of 0.6 V at normal current densities. However, it can be reduced somewhat by doping the anode carbon with various inorganic compounds. A new......
electrolytes. Nickel ferrites have been proposed for aluminium electrowinning. NiFe2O4 anodes with addition of NiO, Ni and Cu were prepared and tested during electrolysis. The metal phase of the anodes corroded..., KVANDE H, STERTEN ?. Aluminium electrolysis. Fundamentals of the Hall-heroult process [M]. Düsseldorf: Aluminium-Verlag, 2001: 353.

A New Contribution to the Theory of Anode Effect in Aluminium Electrolysis邱竹贤摘 要:<正> This paper discusses the general characteristicsof anode effect in aluminium electrolysis and pre-vious theories about the mechanism of anode effect.On the basis of laboratory experiments,the authorsuggests a new contribution to the primary and di-rect reason......
to 1.5. In the Zn-Cu-Cd sulphate solution, the rosy copper was first deposited on the surface of aluminium plate and then the deposited product became grey after a period of electrolysis. The blue colour... sulphate solution, a loose spongy powder product with black colour was obtained, and can be easily detached from the aluminium cathode during electrolysis. In contrast, although rosy copper appeared......
