. The feeding period of CaO was adjusted by the method of electric potential control. At the same time, the factor that affects current efficiency was discussed according to the Ca content of alloys obtained... with the Ca content (mass fraction) of 11.6% can be obtained by electrolyzing for 1 h at the current of 7 A and 740 ℃, and the current efficiency can reach 67.3%. Key words: Al-Ca alloy; liquid aluminium......
) where α is the generation rate of the cathode copper, t/h; η is the current efficiency of the electrolytic cell; k is the copper electrochemical equivalent, 1.185×10-6 t/(A·h); I is the current... for different statistical periods. However, the calculated value is suggested to be compared with the actual production data, and the current efficiency then needs to be revised in order to improve......
