Summary

This paper investigates the microstructural evolution of alkali-activated lunar regolith simulant under in-situ lunar temperatures. The study focuses on the reaction mechanisms of sodium hydroxide and sodium silicate activators, analyzing elemental information, coordination structure, chemical composition, phase assemblage, and pore structure through microstructural characterizations. The results highlight differences in gel product formation and porosity between the two activators. This paper investigates the microstructural evolution of an alkali-activated lunar regolith simulant under in-situ lunar temperatures, focusing on reaction mechanisms using advanced analytical techniques.
