Activities of FexO in Na2O-Al2O3-SiO2-FexO Homogeneous Liquid Slags at 1673 K

摘要

Electrochemical measurements of the solid-oxide galvanic cell of the type Mo/Mo + MoO[2]/ZrO[2] (MgO)/Fe + {Na[2]O-Al[2]O[3]-SiO[2]-FexO} slag/Ag/Fe were conducted at 1673 K in order to obtain the activities of FexO in Na[2]O-Al[2]O[3]-SiO[2]-FexO system. The iso-activity curves for FexO at 1673 K were determined for Na[2]O-(Al[2]O[3] + SiO[2])-FexO pseudo-ternary slags with an Al[2]O[3]/SiO[2] molar ratio of 33/67.
