Experimental data are presented on the high-temperature synthesis of cast materials in the Cr–Al–C system with a maximum content of the MAX phase Cr₂AlC. Experiments were carried out in multipurpose self-propagating high-temperature synthesis (SHS) reactors at an argon pressure p = 5 MPa. The starting mixtures consisted of chromium(VI) and chromium(III) oxides, aluminum, and carbon. It has been shown that varying synthesis parameters may have a significant effect on the phase composition and microstructure of the final products. We have optimized synthesis conditions for the preparation of materials with a maximum content of the MAX phase Cr₂AlC and assessed the effect of acid media on the phase composition of the synthesis products. A material based on the MAX phase Cr₂AlC has been shown to have high resistance to aqueous 30% HCl, 10% HF, and 45% HF solutions. The materials prepared by the SHS metallurgy process have been characterized by X-ray diffraction, X-ray microanalysis, and microstructural analysis.

–A material based on the V₂AlC MAX phase has been obtained for the first time by the method of self-propagating high-temperature synthesis (SHS) using a reaction mixture of vanadium oxide(V) and (IV) powders with aluminum and carbon (graphite). The obtained material was characterized by X-ray diffraction and energy-dispersive X-ray spectroscopy. The Rietveld method was used to perform quantitative analysis. The synthesized material based on the V₂AlC MAX phase is an electrical conductor that demonstrates the metallic behavior of conductivity in the entire measured temperature range of 300–1300 K in the vacuum of 2 × 10^–3 Pa. It has been suggested that the V₂AlC phase makes a decisive contribution to the electrical resistance of the synthesized material that may be caused by the formation of V₂AlC nanolaminate grains contacting with each other in the bulk of the material.

Experimental data are presented on the high-temperature synthesis of cast inorganic materials in the MgO–Al₂O₃ system. Experiments were carried out in multipurpose self-propagating high-temperature synthesis (SHS) reactors at an argon pressure p = 5 MPa. The starting mixtures used in the experiments consisted of molybdenum(VI) and magnesium(II) oxides and aluminum. It has been shown that, varying synthesis parameters, one can control the phase composition and microstructure of the final oxide products. We have optimized synthesis conditions for the preparation of single-phase magnesium aluminate spinel, MgAl₂O₄. The SHS products have been characterized by X-ray diffraction and local microstructural analysis.
