摘要:

月壤是月面原位资源利用(ISRU)的直接对象,而粘结集块岩作为月壤的重要组分,其微观结构直接影响ISRU技术的可靠性。然而,粘结集块岩内部标志性的亚微米/纳米级单质铁(Fe0)和多孔囊泡结构在实验室环境下难以复现,导致现有模拟月壤保真度普遍不足。本研究以嫦娥五号(CE-5)月壤为目标,通过精确矿物匹配与可控原位热还原工艺,重点攻克了玻璃基质中Fe0原位析出的制备难题,成功研制出高保真WUT-1模拟月壤。分析结果显示,WUT-1在化学成分、物相组成及宏观物理性质上与真实月壤高度吻合,并精准复现了非均质微观结构。该研究显著提升了模拟物在微观结构和基础物理化学性质上的科学保真度,可为月面着陆、原位建造及资源提取等关键技术的地面验证提供高可靠性测试材料。

Abstract:

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.
