The paper characterizes JSC-1A lunar simulant using DTA, TGA, XRD, chemical analysis, and Mössbauer spectroscopy. It discusses glass formation and properties, including critical cooling rate and thermal expansion. The simulant's composition is similar to Apollo 17 lunar soil, with Fe2+ and Fe3+ ions.

The text seems to be a technical or system-generated output, possibly from a content delivery network or a document processing system. This paper characterizes JSC-1A lunar simulant using DTA, TGA, XRD, chemical analysis, and Mössbauer spectroscopy. It discusses glass formation and properties, including thermal expansion, glass transition temperature, and softening temperature. The simulant's composition is compared to Apollo 17 lunar soil, and its potential applications for lunar glass and ceramics are explored.
