Layered Metal Borides | MBene Precursor Materials | 200–500 Mesh Options | Standard Packaging: 1 g, 5 g, and 50 g
MAB phases are layered ternary borides composed primarily of a transition metal, an A-site element, and boron. Their structures contain alternating metal–boron layers and A-element layers. This series includes MoAlB, Nb₂SB, Cr₂AlB₂, Fe₂AlB₂, WAlB, Mn₂AlB₂, and multi-metal catalog compositions. The products are suitable for research on MBene precursors, layered crystal structures, thermal stability, advanced ceramics, catalysis, electrochemistry, and related derivative materials.
MAB phases are an emerging class of layered ceramic materials composed of periodically alternating transition-metal boride layers and A-element layers. Similar to MAX phases in their laminated architecture, many MAB materials combine structural anisotropy, high-temperature stability, and the potential for selective reactions. Certain compositions are investigated as precursor systems for two-dimensional MBene-related materials.
This series covers Mo-, Nb-, Cr-, Fe-, W-, Mn-, and multi-metal-based catalog compositions with different A-site elements and boron contents. The products support fundamental structural research, two-dimensional derivative-material preparation, catalysis, electrochemistry, thermal-stability studies, and advanced ceramic development. Actual phase composition, elemental ratios, crystal structure, and secondary phases should be confirmed using batch-specific characterization data.
