Titanium carbide is a hard, corrosion-resistant refractory material with excellent wear and strength characteristics. It registers 9-9.5 on the Mohs scale of hardness and has a face-centered cubic crystalline structure.

It is used for refractory purposes and for making hard alloys and metal-ceramic tools. It has a high melting point, low boiling point, high tensile and compressive strength, good resistance to shock and impact, a high specific heat, and is chemically inert. It also has a low electrical resistivity, which allows it to be used as a conductor of electricity.

A method of producing mechanically resilient titanium carbide (TiC) nano-fibrous felts is disclosed. The process comprises electrospinning a spin dope for making precursor nanofibers; overlaying the nanofibers to make a nanofibrous mat; and chlorinating the resulting TiC-doped carbon (CDC) nano-fibrous felts to remove titanium. The resulting CDC-TiC nano-fibrous felts have a narrow particle size distribution and large surface area and exhibit good purity rates.

A new approach to obtaining a uniform and compact carbide coating on graphite is described. The method involves contacting the graphite with a powdered niobium-titanium alloy, degassing the mixture and the graphite simultaneously, and heating them to a temperature that causes melting, wetting, spreading, and carburization of the niobium-titanium mixture on the graphite. The result is a dense coating that is more adherent than conventional tungsten carbide or titanium oxide.

A corrosion resistant, electrically conductive, non-porous bipolar plate is made from titanium carbide for use in an electrochemical device. The plate is made by blending titanium carbide with a binder material, then molding the blend at an elevated temperature and pressure. One example of a commercial grade is Kentanium, which contains about 82% tungsten carbide and 8% titanium carbide in a cobalt binder, and can have up to 40% nickel or 20% cobalt for parts that need high oxidation resistance.
