Abstract
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.
