Activities of FexO in Na2O-Al2O3-SiO2-FexO Homogeneous Liquid Slags at 1673 K
Abstract
Electrochemical measurements of the solid-oxide galvanic cell of the type Mo/Mo + MoO2/ZrO2 (MgO)/Fe + {Na2O-Al2O3-SiO2-FexO} slag/Ag/Fe were conducted at 1673 K in order to obtain the activities of FexO in Na2O-Al2O3-SiO2-FexO system. The iso-activity curves for FexO at 1673 K were determined for Na2O-(Al2O3 + SiO2)-FexO pseudo-ternary slags with an Al2O3/SiO2 molar ratio of 33/67.
