Laser sintering process of lunar regolith simulants using an aerodynamic levitator by time- and temperature-resolved NPD
We aim to use neutron diffraction to generate the baseline fundamental description of lunar regolith simulants, with a particular emphasis on phase evolution during sintering and cooling. Samples consist of metal-oxides and mineral composites in chemical and shape concentrations according to returned Apollo specimens. Impact melt and agglutinated material is not yet widely present in available simulants for technology verification studies by the wider space community. 3D printed constructions, separation of oxygen and metal, and the extraction of volatiles (water) are application areas to be developed and refined. Heating is seen as the dominant modification process in all processing of regolith. Phase behaviour undergoing laser melting up to 1500 °C is proposed to be investigated, employing an aerodynamic levitator to remove gravity and nucleation influences. Comparisons are made to conventional vanadium can containment. A particular focus is on differences between leading highland simulant providers encompassing varying anorthosite/ agglutinate fractions, as represents the upcoming Artemis landing zone (2025) in contrast to earlier studies dominated by basaltic mare material.
