Iron Aluminum Boride (Fe2AlB2) MAB Phase Powder

Purity: 99+%, Size: 200 mesh

Iron Aluminum Boride is a prominent member of the MAB phase family, distinguished by its orthorhombic crystal structure and its rare combination of metallic conductivity and intrinsic ferromagnetism. Unlike many other ternary borides, Fe2AlB2 features a nanolaminated architecture where Fe-B layers are interleaved with Al atomic planes. This specific configuration allows the material to exhibit significant magnetocaloric effects near room temperature, a property that is highly sought after for sustainable cooling technologies. Its structural robustness is derived from the strong covalent bonding within the Fe-B networks, providing the material with excellent thermal resistance and mechanical durability under high-stress conditions.

Applications

• Magnetic Refrigeration & Cooling:Fe2AlB2 is a leading candidate for active magnetic regenerator (AMR) systems. Due to its significant magnetocaloric effect (MCE) near room temperature and the absence of rare-earth elements, it is used to develop eco-friendly, gas-free cooling devices for both industrial and domestic refrigeration.
• Smart Sensors and Actuators: The material’s sensitivity to magnetic field changes, coupled with its mechanical strength, makes it ideal for high-precision magnetic sensors and transducers. It can be integrated into actuators that require rapid response times and durability in fluctuating thermal environments.
• Protective Coatings for Extreme Wear: Utilizing its high hardness and thermal resistance, Fe2AlB2 is applied as a protective layer for critical components in the mining and automotive industries. It provides a superior barrier against abrasive wear and oxidative degradation in heavy-duty mechanical systems.
• MABene Synthesis: As a layered precursor, Fe2AlB2 is investigated for the synthesis of 2D iron borides. These "MABenes" are researched for their potential in high-surface-area catalysis and as conductive platforms for next-generation electronic devices.
  
• Aerospace Structural Enhancements: The synergy of low density (relative to traditional steel alloys) and high thermal shock resistance allows Fe2AlB2 to be used in aerospace components that are subject to rapid temperature cycles and mechanical vibrations.
• Electromagnetic Shielding: The inherent magnetic properties of the iron sublattices, combined with metallic electrical conductivity, enable the material to effectively absorb and dissipate electromagnetic interference (EMI), protecting sensitive electronic equipment in defense and telecommunications.
