Abstract— In the experiment, plasma–dust clouds were obtained from the substance of the Tsarev meteorite, a simulant of lunar regolith LMS-1D and ilmenite concentrate using a microwave discharge in powder media. For each of the samples, the dynamics of the development of the discharge and the formation of a plasma–dust cloud with subsequent relaxation after the end of the microwave pulse were recorded. From the emission spectra of the plasma and the surface of a solid body, the temperatures of the gas, electrons and surface were determined. A comparison of the phase and elemental composition of the initial samples and samples after exposure to plasma showed that there is no significant change in the composition. However, scanning electron microscopy results clearly indicate spheroidization of the original angular and irregularly shaped particles. The appearance of spherical particles is also observed, the dimensions of which are larger than the linear dimensions of the particles in the original sample. The results obtained indicate the possibility of using such experiments to study chemical and plasma-chemical processes of synthesis and modification of substances under conditions of plasma–dust clouds encountered in space phenomena.

В эксперименте получены плазменно-пылевые облака из вещества метеорита Царев, имитатора лунного реголита LMS-1D и ильменитового концентрата с помощью микроволнового разряда в порошковых средах. Для каждого из образцов зарегистрирована динамика развития разряда и образования плазменно-пылевого облака с последующей релаксацией после окончания микроволнового импульса. По спектрам излучения плазмы и поверхности твердого тела определены температуры газа, электронов и поверхности. Проведенное сравнение фазового и элементного состава исходных образцов и образцов после воздействия плазмы показало, что существенного изменения состава не происходит. Однако результаты сканирующей электронной микроскопии четко указывают на сфероидизацию исходных угловатых частиц и частиц неправильной формы. Также наблюдается появление сферических частиц, размеры которых больше, чем линейные размеры частиц в исходном образце. Полученные результаты указывают на возможность использования таких экспериментов для исследования химических и плазмохимических процессов синтеза и модификации веществ в условиях плазменно-пылевых облаков, встречающихся в космических явлениях.
