Abstract
An electrochemical reaction cell using a solid electrolyte was developed to study the thermodynamic and kinetic behavior of interfacial oxides. Al 2O3 and TiO2 existing between the Fe alloy melt and the magnesia stabilized zirconia solid electrolyte could be controlled using an electrochemical method of an external direct current at 1 823 K. This novel approach could control the electron density near the interface of the oxidesand subsequently the interfacial oxygen. In this study, a direct current of 0.1 ampere resulted in the decomposition of the interfacial oxides and an interfacial oxygen concentration below 3 ppm. Furthermore, morphological observations using EPMA confirmed the interfacial oxide control corresponding to the external electrical potential.
