Influence study of the plasma dynamic method energy parameters on the phase composition of the Al-Mg-O system products

Abstract

This article shows the possibility of obtaining aluminum-magnesium-oxygen system materials by plasma dynamic synthesis. The results of the influence study of the coaxial magnetoplasma accelerator input energy on the phase composition of the plasma dynamic synthesis product are presented. X-ray structural analysis showed the possibility of obtaining nanostructured material with the content of the phases of gamma aluminum oxide and some spinels of different stoichiometry. It was found that with increasing the value of the accelerator input energy, the total percentage of the spinel phases decreases from 12 to 7%. The results of transmission electron microscopy confirmed the absence of the spinel phase MgAl2O4 in the product of plasma dynamic synthesis obtained at a higher value of the input energy.
