6. Titanium carbide is a typical transition metal carbide. Its bonding type is a mixture of ionic, covalent and metallic bonds in the same crystal structure. Therefore, titanium carbide has many unique properties. The crystal structure determines the basic characteristics of titanium carbide such as high hardness, high melting point, wear resistance and electrical conductivity. Titanium carbide ceramics are the most widely developed materials among the transition metal carbides of titanium, zirconium and chromium.
