  Chromium Aluminum Carbide (Cr₂AlC) MAX Phase Micron Powder (99+%, -400 mesh) is an advanced layered ceramic material belonging to the MAX phase family, known for combining metallic and ceramic characteristics within a single crystalline system. Its atomic structure consists of robust chromium–carbon slabs periodically separated by aluminum layers, resulting in a highly ordered nanolaminated architecture.

  This unique structural configuration enables Cr₂AlC to exhibit excellent resistance to oxidation and chemical attack at elevated temperatures. During exposure to oxidative environments, chromium and aluminum synergistically generate stable, adherent oxide layers that act as an effective barrier against further degradation. Unlike conventional ceramics, the intrinsic layered morphology allows localized deformation mechanisms—such as crack deflection and interlayer sliding—leading to improved toughness and machinability using standard tooling.

  Owing to its thermal resilience, electrical conductivity, and structural integrity, Cr₂AlC is increasingly adopted in demanding environments where both mechanical reliability and functional performance are required.

  Applications

  High-Temperature Protective Coatings

  Cr₂AlC is widely investigated as a coating material for components operating under extreme thermal and oxidative stress, such as turbine blades and hot-section engine parts. Its ability to form self-healing oxide layers significantly reduces oxidation and corrosion rates, thereby extending service life in aerospace and industrial gas turbine systems.

  MAX Phase Precursor for MXene Synthesis

  This powder serves as a high-quality precursor for producing chromium-based MXenes (e.g., Cr₂C). Compared to titanium-derived MXenes, chromium-based variants offer distinct magnetic and electronic properties, making them attractive for energy storage devices, EMI shielding, and advanced electronic components.

  Nuclear and Radiation-Resistant Components

  Cr₂AlC demonstrates strong tolerance to neutron irradiation and maintains dimensional stability under severe thermal gradients. These properties make it a promising candidate for nuclear reactor internals, including structural supports and protective cladding materials.

  High-Temperature Electrical Contacts and Substrates

  The combination of ceramic durability with metallic-level electrical conductivity allows Cr₂AlC to function reliably as an electrical interconnect or conductive substrate in high-temperature and chemically aggressive environments.

  Electrochemical and Catalytic Systems

  Cr₂AlC and its surface-modified derivatives are explored as stable catalyst supports in electrochemical applications, including water electrolysis and hydrogen evolution reactions. Its conductive backbone supports efficient charge transfer while maintaining structural durability.

  Biomedical and Functional Surface Engineering

  Emerging studies indicate potential for Cr₂AlC-based coatings in biomedical applications, particularly where antimicrobial behavior and oxidative stability are desired. Its surface chemistry enables the development of durable, bio-functional interfaces for tools and implant coatings.
