Titanium Carbide

Titanium carbide (TiC) has a very high melting-point (3100 C), is extremely hard and strong, and electrical conductive. Because of its electrical conductivity its Ti 2p peak-shape will be asymetric, similar to that for Ti metal (the same peak-shape for the metal is used with good results in the TiC example given below). The Ti 2p3/2 binding energy for the carbide is around 454.9 to 455.1 eV while the C 1s peak for the carbide is around 281.7 to 281.9 eV [1,2,3]. A CasaXPS ready example of titanium carbide can be found here.
