Ta4C3Tx MXene Phase Powder Description
Ta₄C₃Tₓ MXene Phase Powder is a highly conductive, two-dimensional transition metal carbide nanomaterial synthesized primarily through the selective etching of aluminum from the Ta₄AlC₃ MAX phase precursor, typically using hydrofluoric acid or fluoride-containing etchants. This process yields accordion-like multilayered particles with exposed surfaces terminated by functional groups (Tₓ), such as -O, -OH, and -F. The powder exhibits a distinctive metallic luster, excellent electrical conductivity, and good hydrophilicity, facilitating dispersion in aqueous solutions. Its layered structure provides a high specific surface area, while its intrinsic properties include notable mechanical strength, chemical stability, and efficient electromagnetic wave absorption. These characteristics make it a promising candidate for advanced applications in energy storage devices like supercapacitors and batteries, electromagnetic interference shielding, catalytic systems, and sensor technologies.
