Applications

Niobium Aluminum Carbide (Nb2AlC) belongs to the family of Mn+1AXn (MAX) phases with more than 80 members. These are layered, machinable, nanolaminated ternary carbides, nitrides and borides, where M is an early transition metal, A is an A-group element, mainly from groups 13–16 and X is C or N or B. These compounds possess hexagonal crystal structure with space group P63/mmc (space group number: 194), where M atoms are in a near closed packed arrangement and are intercalated with A-group atomic layers, with the X-atoms residing in the octahedral sites between the M layers. These atomic arrangements give the MAX phases an effective laminated layered structure that leads to the naming of the MAX phase as nanolaminates. MAX phases possess a unique combination of properties, both metallic and ceramic in nature due to the layered structure. Metallic properties can include good thermal and electrical conductivities, good thermal shock resistance, excellent damage tolerance, and good machinability. Ceramic properties include low density, elastic rigidity, oxidation and creep resistance, and the ability to maintain strength up to very high temperatures.

Nb2AlC has attracted considerable interest. It not only possesses decent mechanical and thermal properties but also shows a superconducting transition at 400 mK for the thin film form. All of these properties render Nb2AlC a promising material for high-temperature structural and functional applications.
