Applications

Vanadium Aluminum Carbide (V₄AlC₃) belongs to the family of M_n+1AX_n (MAX) phases with more than 80 members. These are layered, machinable, nanolaminated ternary carbides, nitrides and borides, where M is an early transition metal, A is an A-group element, mainly from groups 13–16 and X is C or N or B. These compounds possess hexagonal crystal structure with space group P6₃/mmc (space group number: 194), where M atoms are in a near closed packed arrangement and are intercalated with A-group atomic layers, with the X-atoms residing in the octahedral sites between the M layers. These atomic arrangements give the MAX phases an effective laminated layered structure that leads to the naming of the MAX phase as nanolaminates. MAX phases possess a unique combination of properties, both metallic and ceramic in nature due to the layered structure. Metallic properties can include good thermal and electrical conductivities, good thermal shock resistance, excellent damage tolerance, and good machinability. Ceramic properties include low density, elastic rigidity, oxidation and creep resistance, and the ability to maintain the strength up to very high temperatures.

V₄AlC₃ is an emerging vanadium-based MAX material that possesses a thicker V₄C₃ component and higher corrosion resistance than that of the V₂AlC MAX material. It is a precursor of V₂O₅/C composite, which is a potential cathode material for Zn-ion batteries (AZIBs). It is also an efficient heterogeneous catalyst for solvent-free aerobic oxidation of toluene to benzaldehyde.
