最近的研究表明，月球风化层与镁形成可燃的铝热剂型混合物。这些混合物的燃烧可以用来生产月球上的建筑材料。本文主要研究了降低JSC-1A模拟月球风化层混合物中镁的含量，并提高这些混合物的燃烧产物的密度和强度。研究了JSC-1A/Mg混合球团在氩气和硅粉中的燃烧情况。预热到100摄氏度，燃烧所需的镁的最低浓度从10 wt.%降低到8 wt.%。将球团浸入二氧化硅中可提高产品强度。进行了SHS压实实验，在燃烧过程结束后立即对产物进行准等静压。这导致了产品密度的显著增加。抗压强度超过10 MPa，高于普通砖（5 MPa）。(c) 2013年燃烧研究所。Elsevier Inc.出版。版权所有。
It has been shown recently that lunar regolith forms combustible, thermite-type mixtures with magnesium. Combustion of these mixtures could be used for the production of construction materials on the Moon. The present paper focuses on decreasing magnesium content in mixtures based on JSC-1A lunar regolith simulant and increasing the density and strength of the combustion products of these mixtures. Combustion of JSC-1A/Mg mixture pellets was studied in argon gas and in silica powder. Preheating to 100 degrees C decreased the minimum concentration of magnesium, required for combustion, from 10 wt.% to 8 wt.%. Submerging the pellets into silica increased the product strength. SHS compaction experiments were conducted, which involved quasi-isostatic pressing of the products immediately after the end of the combustion process. This resulted in a significant increase in the product density. The compressive strength exceeded 10 MPa, i.e., was higher than that of common bricks (5 MPa). (c) 2013 The Combustion Institute.
