Features: Niobium aluminum carbon (Nb2AlC) is a new member of ternary layered ceramic materials, which combines many advantages of metals and ceramics: low hardness, machinability, high modulus, high strength, excellent damage tolerance and thermal shock resistance, high electrical conductivity and thermal conductivity. More importantly, niobium aluminum carbon has extremely excellent high-temperature mechanical properties and has broad application prospects in high-temperature structural materials, electrodes or electric brush materials. However, the low room temperature strength and hardness of niobium aluminum carbon limit its application as a structural material.

1.Nb₂CTx MXene precursor:LiF/HCl directly etches epitaxial films to give Li-intercalated Nb₂CTz (Halim 2019); Nb₂CTx has been used as a Li-ion battery anode (JACS 2013); the Lewis acidic molten-salt etching process has been resolved by in-situ XRD (Chem. Mater. 2025). Note:Nb₂CTz films are not metallicand show variable-range hopping at low temperature
