J. Cent. South Univ. (2018) 25: 754-763 DOI: https://doi.org/10.1007/s11771-018-3780-1 Effect of additives on anode passivation in direct electrolysis process of copper–nickel based alloy scraps LI... powder aggravated the anode passivation. In a certain range of the glue concentration ≤8×10–6 or thiourea concentration ≤4×10–6, the increase of glue or thiourea concentration increases the anode......
anions reacts with carbon to form a high-resistance CF film on the anode surface at a high potential. The passivation potential is 3.28 V in 0.5% alumina-containing electrolyte, and the passivation... electrolysis; perfluorocarbons; anode passivation 1 Introduction In the primary aluminum production by the Hall-Héroult process, a departure from normal cell operation known as the anode effect (AE......
