Abstract:

New analytical method for the study of electrochemical kinetics has been applied to the slag-metal system at high temperature.
By comparing with previous analytical methods for the electrode reaction, this method has shown that the phenomena in the electrode reaction at the slag-metal interface are more accurately and reasonably interpreted.
By analyzing current-time curves obtained by the potential step method, kinetic parameters were derived from an exact solution of the electrode kinetic equation using Deming's least squares method.
