Titanium carbide: a versatile high-performance material

 

Overview

Titanium carbide (TiC) product is a typical transition metal carbide with high hardness, high melting point, good chemical stability, and electrical and thermal conductivity. These characteristics make titanium carbide one of the indispensable and important materials in industry. Titanium carbide usually has a gray metallic appearance, a face-centered cubic lattice structure, a melting point of about 3140°C, a hardness greater than 9 (second only to diamond), and a relative density of 4.93.

Preparation method

Titanium carbide can be prepared by a variety of methods, including but not limited to:

 

Direct carbonization method: At high temperatures, titanium carbide is generated by a direct reaction of metallic titanium and carbon.

Chemical vapor deposition (CVD): Using a gas precursor containing titanium and carbon to deposit a titanium carbide film at high temperatures.

Powder metallurgy method: Mix titanium powder and carbon powder and react under high temperature and high-pressure conditions.

Liquid phase etching method: Use a specific solution to remove certain elements in the original material (such as Ti3AlC2) to prepare titanium carbide nanosheets or their derivatives.

Performance characteristics

High hardness: Titanium carbide has an extremely high hardness, which makes it an ideal wear-resistant material, especially suitable for manufacturing knives, cutting tools, and bearings.

Thermal stability: Even in high-temperature environments, titanium carbide can make the stability of its physical and chemical properties, so it is often used as a high-temperature thermal barrier coating.

Chemical stability: Titanium carbide is stable to air at lower temperatures and is not easily corroded by most chemicals. It can only be dissolved in strong acids such as nitric acid and aqua regia.
 

Application areas

Manufacturing: Titanium carbide is widely used in the manufacture of cemented carbide, cutting tools, molds and so on, because of its high hardness and wear resistance.

Aerospace: The lightweight and high-temperature resistance of titanium carbide makes it an better choice for manufacturing aircraft engine components.

Automotive industry: Used to manufacture engine components, brake system components, etc., to improve vehicle safety and durability.

Electronic devices: Due to its good conductivity, titanium carbide is used as a conductive coating or contact material in microelectronics.

Biomedical Engineering: Titanium carbide nanomaterials are used to construct biosensors for detecting biomolecules, such as blood sugar level monitoring.

Environmental Protection: Titanium carbide and its derivatives can be used for photocatalytic decomposition of harmful substances, which helps protect the environment.
 

Conclusion

As a high-performance material, titanium carbide has shown great application potential in many industries. With the continuous development of preparation technology and application fields, titanium carbide is expected to play an important role in more emerging fields in the future.
