This research line focuses on the high-temperature behaviour of lunar regolith and regolith-derived glasses in the context of in-situ resource utilization (ISRU) for lunar infrastructure. We investigate the physicochemical transformations, phase evolution, and rheological behaviour of regolith under thermal conditions relevant to 3D printing and sintering. High-temperature experiments are used to constrain the rheology of molten regolith, the kinetics of partial melting, and the sticking and coalescence behaviour of regolith particles during sintering as a function of grain size, temperature, and time. Mechanical testing of thermally processed materials is then employed to identify processing windows that yield mechanically viable engineering products from regolith simulants.
