Abstrakt: Due to the development of the chemical industry, the need to obtain high-purity monodisperse nanoparticles is increasing. Therefore, it is necessary to choose the right method for obtaining them. The paper demonstrates a unique method, induction flow levitation, which allows a large list of metal nanoparticles to be obtained using one installation. In this work, magnesium nanoparticles are obtained using this method. The morphology is studied using scanning electron microscopy, where the resulting nanoparticles are clusters of primary particles. Energy-dispersive analysis shows that the surface of magnesium nanoparticles after interaction with atmospheric air is completely covered with a small layer of oxide. Analysis of the phase composition shows that the powder consists of magnesium without traces of oxide. Mass spectrometry with inductively coupled plasma shows a purity of the obtained particles of 99.99%. The characteristics of the porous structure are determined by low temperature porosimetry. The size of the obtained particles does not exceed 40 nm, and the average size is 23 nm. The used method of obtaining nanoparticles demonstrates high productivity (up to 50 g/h) and continuity of the process of obtaining nanoparticles (NP), the ability to control the size of the obtained nanoparticles (NP) in a wide range, noncontact heating, which leads to a high purity of the resulting product confirmed by mass spectrometry with inductively bound plasma.
