Chromium Aluminum Carbide (Cr2AlC) MAX Phase Micron Powder

Purity: 99%, Size: -400 mesh

Chromium Aluminum Carbide is a nanolaminated ternary compound that exemplifies the unique synergy of the MAX phase family. Its crystalline architecture is defined by Cr-C layers characterized by strong covalent bonds, interleaved with layers of Al atoms. This specific atomic arrangement grants the material its signature "metal-ceramic" duality. A defining metallurgical feature of Cr2AlC is its exceptional chemical stability in oxidizing atmospheres, where the chromium and aluminum work in tandem to form protective surface oxides. Unlike standard brittle ceramics, its layered structure allows for energy dissipation through delamination and kinking mechanisms, facilitating high damage tolerance and the ability to be machined with conventional tools.

Applications

• Environmental Barrier & Thermal Coatings: Cr2AlC is a primary candidate for high-temperature coatings in gas turbines. Its ability to maintain a stable, adherent oxide scale at elevated temperatures prevents the underlying superalloys from undergoing severe oxidation and hot corrosion, significantly extending component life in aerospace engines.
• Next-Generation MXene Precursor: This powder serves as the critical feedstock for synthesizing Cr2C MXenes. These 2D derivatives are increasingly utilized in energy storage and electromagnetic interference (EMI) shielding, where the magnetic potential of chromium provides unique functional advantages over titanium-based alternatives.
• Nuclear Reactor Internals: Due to its inherent radiation tolerance and the ability to withstand extreme thermal gradients without fracturing, Cr2AlC is explored for structural use in nuclear technology. It remains dimensionally stable under neutron irradiation, a requirement for core components and fuel cladding.
• High-Temperature Electrical Interconnects: The material’s metallic-level electrical conductivity, combined with its resistance to degradation at high heat, makes it ideal for conductive ceramic substrates and electrical contacts that must operate in aggressive industrial or aerospace environments.
• Electrochemical Catalysis:Cr2AlC and its etched derivatives act as robust catalyst supports. Its surface chemistry facilitates efficient electron transfer during water-splitting reactions and other electrochemical processes, providing a durable platform for hydrogen production.
• Functional Biomedical Surfaces: The material is investigated for biomedical surface engineering, particularly for antimicrobial coatings. Its unique surface energy and chemical resilience allow for the development of implants or tools with radical-scavenging properties to reduce oxidative stress at the bio-interface.
