We review the containerless-levitation techniques for thermophysical property measurements of high-temperature liquids. Particularly, we describe details of recent research using the techniques under microgravity in International Space Station (ISS). Thermophysical properties of high-temperature liquids are needs for industrial process control design of high temperature material processes by the numerical simulations. Therefore, their temperature dependence is necessary. For the requirements, their measurements should be in high temperature regions. In high temperature regions, the containerless levitation under microgravity has advantage for thermophysical properties measurements of liquid samples. In this article, we focus on the containerless levitation techniques in ISS for thermophysical properties measurements of high temperature alloy’s liquids, and also the interfacial tension between iron melt and molten oxide.
