The utilization of lunar regolith for construction on the lunar surface has become a critical challenge in the field of in-situ resource utilization. This study proposes a lunar regolith manufacturing method using a high-performance resin binder, which is characterized by high regolith content and forming strength. A combined resin material with both thermosetting and photosetting properties was developed and mixed with lunar regolith to create a regolith slurry. This slurry can be directly molded or additively extruded into green bodies with specific structures. These green bodies can self-cure under the high temperatures and ultraviolet radiation present during the lunar daytime, thereby reducing energy requirements and meeting the demands of lunar construction. The study thoroughly examines the material forming processes, investigating the effects of various additive types and contents, regolith mass ratios, and process parameters on the properties of the slurry and the formed specimens. The mechanical performance and microstructure of the formed samples were also analyzed. The lunar regolith mass ratio reached up to 90 wt.%, with the highest compressive strengths exceeding 60 MPa for cast specimens and 30 MPa for printed samples. This technology shows significant potential for contributing to in-situ lunar regolith-based construction in future lunar missions.

Influences of particle size and composition on the hydrolysis behavior of MgO·nAl2O3 spinel

Ceramics International 2025年

作者： Cao, Mengying Tu, Guangsheng Huang, Qing Liao, Jiaxing Jing, Zhengyang Chen, Bowen Tu, Bingtian Wang, Hao Wang, Weimin Fu, Zhengyi State Key Lab of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Hubei Wuhan430070 China Hubei Longzhong Laboratory Hubei Xiangyang441000 China

The hydrolysis characteristic of MgO·nAl2O3 powders poses significant challenges for fabricating large-sized and complex-shaped transparent ceramic components. In this work, the hydrolysis behavior of MgO·nAl2O3 powders with designed particle size and chemical composition was systematically investigated. The results ascertained that coarse MgAl2O4 powders synthesized at higher temperatures exhibited reduced surface-active sites, and alumina-rich spinel surfaces exposed decreased unsaturated Mg atoms that catalyze water dissociation. The OH− concentrations in MgAl2O4-coarse and MgO·1.8Al2O3 suspensions were 63 % and 32 % of that in MgAl2O4-fine one, respectively, indicating an effective inhibition of the hydrolysis reaction. Ultimately, the hydrolysis mechanism of MgO·nAl2O3 was elucidated, where the boehmite protective layer (∼15 nm) formed on the particle surface after hydrolysis. This study provides a fundamental understanding of the surface properties and hydrolysis behavior of MgO·nAl2O3, which is of great significance for the preparation of spinel transparent ceramics using aqueous gel-casting. © 2025 Elsevier Ltd and Techna Group S.r.l.
