Theoretical Decomposition Voltage for Related Substance on Molten Salt Electrolysis Method to Remove Steel Surfaces of Sulfide Inclusions
The theoretical decomposition voltage (EMF) for substances in FeS-CaCl2-NaCl-KCl system was figured out. The results indicate that the EMF increases in sequence of FeS, CaCl2, NaCl and KCl with inert anodes, and it drops with rising of temperature, increases with decreasing of FeS concentration. Under a lower FeS concentration, as a result, the anode effect can occur. Fe would be separated out from cathode and Cl2 would be separated out from anode first in electrolytic desulfurization process.
