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 nitric, hydrofluoric, or aqua regia solutions, as well as in alkaline oxidation solutions.
Titanium carbide, a gray iron crystal with metallic luster that belongs to a simple cubic structure NaCl type, is a crystal of a cubic structure. The covalent bonding between the titanium and carbon atoms in TiC is equivalent to strong atoms. It has many properties similar to metals. These include high melting and boiling points, as well as hardness. Diamond is the only other material that can rival its hardness.

Titanium carbide has excellent thermal conductivity and electrical conductivity. This powder is superconductive even at low temperatures. TiC can be used in a wide range of 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 Titanium dioxide and Carbon Black is mixed proportionally and then pressed into a tube furnace in hydrogen using either a horizontal carbon furnace or a tube furnace vertical. At 1900-2300degC reduction to obtain block of TiC is performed, followed by pulverization for titanium carbide product. Or using carbon and sponge titanium as raw materials. Carbon and sponge Titanium (or Titan alloy, recovered titanium waste from carbide liquid solution) are fully mixed, heated to 1500-1700degC, in a highly-pure hydrogen stream.

Direct carbonization of Titanium Metal:
Titanium powder (reduced with sodium or decomposed by titanium hydride; less than 325 mesh), mixed with carbon-black, is molded and heated at 1500-17degC using a high-purity stream of hydrogen in order to infiltrate carbon. The reaction temperature, holding time and particle size are dependent on the type of material and performance.

Gas phase reaction method:
Hydrocarbons containing hydrogen (benzene and methane) are mixed into the steam of titanium chloride. 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 form of titanium carbide differs depending on the reaction conditions.
