摘要

通过在熔融NaCl中自蔓延高温合成VO2/Mg/Al/C混合物，然后在稀盐酸中浸出制备V2AlC粉末。合成产物包括V2AlC、钒铝化物和钒碳化物、MgO和MgAl2O4。发现相组成依赖于镁和碳的含量。确定了制备V2AlC MAX相的最佳配比和酸浸条件。

SHS of V2AlC Ceramics Using VO2 as a Starting Material

V₂AlC powder was prepared through self-propagating high-temperature synthesis of VO₂/Mg/Al/C mixture in molten NaCl followed by leaching in dilute hydrochloric acid. The synthesized product included V₂AlC, vanadium aluminides and carbides, as well as MgO and MgAl₂O₄. The phase composition was found to be magnesium and carbon content dependent. Optimum component ratios and acid leaching conditions were determined for the successful synthesis of V₂AlC MAX phase.

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
