The Properties And Applications of Titanium Carbide Powder

Titanium carbide TiC has the chemical symbol TiC. It is a metallic-looking steel gray carbide crystal with thermal and electrical conductivity.

Titanium Carbide Powder Properties

Titanium carbide, a compound that is extremely hard and has a melting point of over 900°C, is also a highly corrosive material. It has a hardness that is second only to the diamond, but it does not have strong magnetic properties. Titanium carbide has a low magnetic property and is not soluble with water.
Titanium carbide reacts with pure oxygen at 1150degC. Titanium carbide is a solid that has the same crystal structure as TiN or TiO.




Titanium Carbide Applications

Titanium carbide can be used for a variety of purposes. As the technology for the microwave synthesis nano-TiC is improved and industrialized, the performance and applications of using the nano-TiC to prepare the corresponding materials are greatly enhanced.

1. Use of titanium carbide as a multiphase material
Titanium carbide ceramics, also known as super hard tool materials (TiC), are composite materials made from TiC, and TiN. WC, and A12O are other raw materials used to make the materials. These materials, which have a high melting temperature, high hardness and excellent chemical resistance, are used for cutting tools, wear-resistant components and other products. It is a material that has excellent electrical conductivity and is therefore preferred for the electrode.

2. Titanium carbide can be used as a coating material
Titanium carbide has many uses, such as anti-tritium coating for fusion reactors and electrical contact material, or roadheader picks. A layer of titanium carbide can also increase the life of a tool by up to 3-5 times.

3. Titanium carbide can be used to make foam ceramics
As a filter ceramic foam can remove the inclusions that are present in different fluids. The filtering process is done by agitation, and then adsorption. Titanium carbide alloy foam ceramics offer higher hardness, strength, thermal conductivity (including electrical conductivity), heat resistance, and corrosion resistance compared to oxide ceramic foam.

4. Titanium carbide can be used to make ceramics that emit infrared light
Titanium carbide, an intermetallic material, is usually chemically stable and doesn’t change its valence, making it a great choice for applications in high temperatures.

Introduction to The Preparation Methods of Titanium Carbide Powder

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.
