Titanium carbide The light gray crystals are cubical and have a high degree of chemical stability. Titanium carbide reacts little with hydrochloric and sulfuric acids. However, it can dissolve in aqua regia or nitric, hydrofluoric, and nitric-acetic acid solutions.
Titanium carbide, a gray iron crystal with metallic luster that belongs to a simple cubic structure NaCl type, is a simple cubic crystal. The covalent bonding between the titanium and carbon atoms in TiC is equivalent to strong atoms. It shares several properties with metals including high melting and boiling points, hardness, and high boiling temperatures. Diamond is the only other material that can rival its hardness.

Titanium carbide has excellent thermal conductivity and electrical conductivity. This powder is superconducting even at low temperatures. TiC can be used in many applications, including the production of heat-resistant metals, cemented carbides, antiwear materials, high temperature radiation materials, and high-temperature vacuum devices. There are many other applications in different fields.

Titanium carbid powder preparation methods:

As raw materials, titanium dioxide and carbon black are used.
The dry powder mixture of high-purity titania dioxide and carbon black is mixed proportionally, then press-formed under a hydrogen-filled atmosphere in either a horizontal or vertical carbon tube. At 1900-2300degC reduction to obtain block of TiC is performed, followed by pulverization for titanium carbide product. Alternatively, carbon black and sponge titanium can be used as raw materials. The sponge Titanium (or Titan alloy, or titanium waste recovered in carbide solid solutions) and carbon are combined in the proportions specified, then heated to 1500-1700degC using a high-purity hydrogen stream.

Direct carbonization of Titanium Metal:
The carbon is then infiltrated with a high-purity stream of hydrogen. The reaction temperature, holding time and particle size are dependent on the raw material.

Gas phase reaction method:
Hydrocarbons such as benzene and methane are mixed into the steam from titanium tetrachloride. After induction heating (or other methods), the steam is sent to deposit titanium carbide on the substrate. The reaction precipitates titania carbide on substrate. The precipitated titanium carbide has a different form depending on the reaction conditions.
