Features of Max Phase Niobium aluminum carbide Nb2AlC Max MXene Composite Material Nb2AlC CAS 60687-94-7
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of Max Phase Niobium aluminum carbide Nb2AlC Max MXene Composite Material Nb2AlC CAS 60687-94-7
Max Phase Niobium Aluminum Carbide (Nb2AlC), also known as MXene composite material, is a high-performance ceramic material with the chemical formula Nb2AlC and the CAS number 60687-94-7. This extraordinary material belongs to the family of two-dimensional (2D) transition metal carbides, called MXenes, which were first discovered in 2011 by the groundbreaking research of Dr. Jun Lou at Georgia Tech.
MXenes are a class of materials derived from the exfoliation of MAX phases, which consist of transition metal carbides or nitrides. The name “MAX” stands for Metal (M) – A cation (A) – X anion (carbon or nitrogen). In the case of Nb2AlC, M refers to niobium (Nb), A is aluminum (Al), and X is carbon (C). The layered structure of Nb2AlC MXene consists of alternating layers of Nb and Al atoms sandwiched between sheets of carbon atoms, forming a unique atomic arrangement.
The key characteristics of Nb2AlC MXene make it highly attractive for various applications. It exhibits exceptional mechanical properties, such as high strength and stiffness, due to its strong covalent bonds between the metal and carbon atoms. This results in a lightweight yet robust material, making it suitable for aerospace, automotive, and defense industries where weight reduction and structural integrity are crucial.
Moreover, Nb2AlC is known for its excellent thermal conductivity, which enables efficient heat dissipation, making it ideal for electronic components, such as microchips and sensors, where thermal management is critical. Its electrical conductivity, influenced by the presence of oxygen vacancies or intercalated ions, can be tuned to achieve both metallic and semiconducting behavior, opening up possibilities for flexible electronics and energy storage devices.
Another notable feature is its supercapacitor performance. MXenes, including Nb2AlC, have a high surface area and abundant reactive sites, which enhance their ability to store and release charge quickly. This makes them promising candidates for developing high-power and high-energy density capacitors.
In addition to these electrical and thermal properties, Nb2AlC MXene demonstrates chemical stability and resistance to corrosion, which is advantageous in harsh environments. It has shown potential applications in catalysis, water purification, and even as a protective coating for metals to prevent corrosion.
The synthesis of Nb2AlC MXene typically involves etching MAX phase precursors in strong acid solutions, followed by exfoliation to produce individual nanosheets. However, there is ongoing research to develop more cost-effective and scalable methods to produce large quantities of MXene for commercial use.
In summary, Nb2AlC Max MXene composite material, with its unique combination of mechanical, thermal, electrical, and chemical properties, is a versatile and promising material that holds great potential in various industries, from electronics to energy storage and environmental applications. As researchers continue to explore its full capabilities, the future of Nb2AlC MXene looks bright, revolutionizing the way we design and engineer modern technologies.
