Preparation method of component-controllable simulated lunar soil based on thermally induced phase change
By optimizing the mixing ratio through thermal phase change and nonlinear programming models, the mineral phase composition of the simulated lunar soil is precisely controlled, which solves the problem of insufficient mineral phase control in the existing simulated lunar soil preparation technology. This achieves a high degree of realism between the simulated lunar soil and the target lunar soil in many aspects, meeting the ground experimental requirements of ISRU technology.

AI Technical Summary
Existing simulated lunar soil preparation technology cannot precisely control the mineral phase composition, resulting in significant differences in thermodynamic properties and chemical behavior compared to real lunar soil during high-temperature chemical reactions and phase transitions. Furthermore, the batch-to-batch consistency of raw materials is poor, failing to meet the ground-based experimental requirements of ISRU technology.
Basalt raw materials are melted, quenched, and heat-treated through a thermally induced phase transformation process. By combining a nonlinear programming model to optimize the mixing ratio, the contents of plagioclase, pyroxene, olivine, and amorphous phases are precisely controlled, thereby achieving controllable formulation of simulated lunar soil components.
The prepared simulated lunar soil is highly matched with the target lunar soil in terms of mineral phase composition, microstructure, optical properties and thermal properties, which solves the problem of accuracy and consistency of simulated lunar soil in ISRU technology research in the prior art, and provides high-fidelity ground experimental materials.
