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 be dissolved by aqua regia or nitric, hydrofluoric, and nitric-fluoric solutions.
Titanium carbide, a gray iron crystal with a metallic luster that belongs to naCl cubic structure, is a simple cubic crystal. 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 a high thermal conductivity and is superconductive at low temperatures. TiC can be used to produce cermets (heat-resistant alloys), cemented carbides (anti-wear materials), high-temperature radiation materials, and other high temperature vacuum equipment. 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 vertical carbon furnace. At 1900-2300degC reduction to obtain block of TiC is performed, followed by pulverization for titanium carbide product. Or using sponge titanium and carbon as raw materials. The sponge Titanium (or titanium alloy, titanium waste recovered in carbide solid solutions) and the carbon black are completely mixed in proportion and heated to 1500-1750degC in high-purity hydrogen streams, finally obtaining titanium carbide.

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 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. Different reaction conditions (such as reaction temperature, reaction gas concentration, and gas flow rate) and different precipitation forms of titanium carbide are observed.
