Vanadium Aluminum Carbide (V₂AlC) MAX Phase Micron Powder
APS: 325 Mesh, Purity: 99+%
Vanadium Aluminum Carbide is a 211 MAX phase material characterized by hexagonal P6₃/mmc crystal symmetry. Its layered microstructure is composed of edge-sharing V₆C octahedral layers separated by aluminum atomic sheets. V₂AlC exhibits outstanding damage tolerance and unique kink-based nonlinear elastic behavior. This enables the material to absorb and dissipate mechanical energy through the development of incipient kink bands (IKBs), preventing sudden brittle fracture and enhancing structural durability.

Applications
MXene Synthesis: V₂AlC is an essential precursor for producing Vanadium Carbide MXenes (V₂CTₓ). Compared with conventional Ti-based MXenes, V-based MXenes provide higher theoretical capacity for alkali metal ions, making them promising materials for advanced battery anodes and pseudocapacitive energy storage systems.
Electrochemical Sensing and Biosensing: The vanadium-rich surface of V₂AlC and its derived MXenes demonstrates excellent electrocatalytic performance. It is widely studied for biomolecule detection, including glucose and neurotransmitters, as well as heavy metal ion monitoring in environmental applications.
Nuclear and Radiation Resistance: V₂AlC offers potential applications in nuclear engineering due to its layered structure, which provides improved management of radiation-induced defects and helium retention compared with conventional ceramic materials. It is being explored as a candidate material for Gen-IV nuclear reactor cladding.
High-Temperature Oxidation Protection: Under elevated temperatures, V₂AlC forms protective oxide layers that enhance oxidation resistance. It is utilized in specialized high-temperature coatings where structural stability, thermal fatigue resistance, and metallic conductivity are required.
Hydrogen Evolution Reaction (HER) Catalysis: The transition metal sites within the V₂AlC structure enable efficient charge transfer for water-splitting reactions. Its chemical stability makes it a reliable catalyst support for both acidic and alkaline electrolyte environments.
