一种含粘结集块岩的高保真嫦娥五号模拟月壤OA

Lunar regolith is the primary object for in-situ resource utilization(ISRU),and agglutinates,as a critical component,possess a complex microstructure that directly dictates the reliability of ISRU technologies.However,the sub-micron/nanoscale metallic iron(Fe0)and porous vesicular structures within agglutinates are extremely difficult to replicate under laboratory conditions,resulting in a general lack of scientific fidelity in existing lunar regolith simulants.Targeting the Chang'e-5(CE-5)lunar regolith,this study successfully developed a high-fidelity simulant,WUT-1,through precise mineral matching and a controllable in-situ thermal reduction process,specifically overcoming the challenge of in-situ Fe0 precipitation within the glass matrix.Analytical results demonstrate that WUT-1 is highly consistent with the authentic lunar regolith in terms of chemical composition,phase mineralogy,and macro-physical properties,while accurately reproducing the heterogeneous microstructure.This research significantly enhances the scientific fidelity of the simulant in microstructure and fundamental physicochemical properties,providing high-reliability testing materials for the ground validation of key technologies such as lunar landing,in-situ construction,and resource extraction.
