V2AlC is a member of vdW MAX layered material system. Similar to graphite and MoS2, the MAX phases are layered and have the general formula: Mn+1AXn, (MAX) where n = 1 to 3, M is an early transition metal, A is an non-metal elements and X is either carbon and/or nitrogen. In this particular case, M=V, A=Al, and X=C with n=2.
World's first electronic and optical grade commercial layered MAXene phase V2AlC materials: V2AlC MAX phase has been synthesized at our facilities using large reactor chemical vapor deposition to yield World's highest purity (99.999% or higher guaranteed) and layered MAX phases. The MAX phases are electrically and thermally conductive due to their metallic-like nature of bonding. They are excellent for research quality materials as 2D metals, battery applications, supermetallicity, thermal physics, or as precursors for MXene production. They have been also subject to research for isolating single layer Al (alumine) owing to isolated Al layers (see atomistic views). V2AlC product consists of microsized layered crystals that measure from 2 microns to 100 microns in size (see SEM images below). Each order contains large volume 1000 mg of high purity and layered V2AlC MAXenes sealed under inert Ar gas. The product has been perfected in the last years to reach guaranteed 2:1:2 V:Al:C ratios and exhibit an extraordinary environmental stability. XRD peaks are rather sharp and SEM images clearly exhibit layered nature of the flakes. Each crystallite can be exfoliated either using conventional tape exfoliation or alternatively liquid phase exfoliation technique.
If you have specific type of new MAXene and MXene phases in mind please contact us. Our research and development team will be happy to design, synthesize, and provide with new types of materials on demand.
