Multi-Element Layered Ceramic Materials | Nominal Purity ≥99% | 200–500 Mesh Options | Standard Packaging: 1 g, 5 g, and 50 g
This series includes Ti₃AlCN, Cr₂VAlC₂, Ti₃TaAlC₂, TiNbAlC₂, Ti₄VAlC₂, Th₂V₁.₅AlC₂, TiV₂AlC₂, and two Ti₃AlC₂ configurations. These materials are suitable for research on MAX-phase structures, elemental site occupancy, interlayer bonding, sintering, coatings, composites, and functional properties.
Ternary MAX phases of the 312 type are commonly represented by the general formula M₃AX₂, where M is a transition metal, A is a main-group element, and X is C, N, or a mixed C/N system. Their structures consist of alternating M–X and A layers, making them suitable for studying how elemental composition, stoichiometry, site occupancy, and interlayer interactions influence material structure and performance.
This series includes conventional Ti₃AlC₂, carbonitrides, multi-metal M-site materials, and special-composition products. Some catalog models do not follow an exact integer M₃AX₂ stoichiometry. Their actual structures, primary-phase content, elemental occupancy, and secondary-phase composition should be confirmed using batch-specific XRD, elemental analysis, and microscopic characterization.
