Electromagnetic and electrostatic levitation techniques have been utilized for the last few decades to process metastable and highly reactive materials. Main fields of application include thermophysical properties, solidification, and transport phenomena of molten metals, which are of critical importance to better understand and control manufacturing processes dealing with molten metals, such as casting, welding, and additive manufacturing. This paper addresses part of our international collaborative work with NASA, European Space Agency, German Aerospace Center, and Japanese Aerospace Exploration Agency to support containerless experiments aboard the International Space Station. Along with space experiments, our recent work using an electrostatic levitator to unveil the liquid structure of aqueous sodium sulfate solutions (the most damaging salt to civil structures) is also introduced.
