In-Plane Ordered Multi-Metal MAX Phases | 200 and 400 Mesh Options | Standard Packaging: 1 g, 5 g, and 50 g
This series includes (Mo2/3Y1/3)2AlC and (Mo2/3Sc1/3)2AlC. These materials are suitable for research on i-MAX crystal structures, in-plane M-site ordering, elemental occupancy, interlayer bonding, powder sintering, selective reactions, and two-dimensional layered derivative materials.
i-MAX phases are multi-metal systems derived from the layered structure of conventional MAX phases. The letter “i” generally indicates that the transition-metal atoms exhibit a specific in-plane ordering pattern within the M layers. These materials usually contain two M-site elements with different atomic sizes or chemical characteristics and are suitable for studying M-site arrangement, local lattice distortion, interlayer bonding, and selective-reaction behavior.
In this series, Mo is the primary M-site element, while Y or Sc is introduced to form the nominal composition (Mo2/3M′1/3)2AlC. Catalog formulas indicate nominal composition only. The actual degree of M-site ordering, primary-phase content, elemental distribution, and secondary-phase composition should be confirmed using batch-specific XRD, elemental analysis, and microscopic structural characterization.
