Abstract Scope |
Liquid iron (Fe) and molten oxides, including Fe-oxides, are generally considered to be immiscible; therefore, interfacial phenomena are intriguing from both scientific and technological perspectives, particularly in the steel industry. We have been studying these interfacial phenomena using core-shell droplets of molten oxide and liquid Fe in the electrostatic levitation furnace (ELF) onboard the International Space Station (ISS). After the samples returned to Earth from the ISS, we observed a reduction in the core Fe volume through X-ray radiography. Additionally, we noted the spreading of core Fe into the shell oxide components. This behaviour may be attributed to the oxidation of liquid Fe at the interface with the molten oxide. Based on these findings, we discuss the reactions and mass transfer occurring at the interface between liquid Fe and molten oxides. |
