Titanium Nitride Properties

What is Titanium Nitride TiN Powder: 

Titanium Nitride formula is TiN. Titanium Nitride is a very hard ceramic material, usually used as a coating for titanium alloys, steel, carbides, and aluminum components to improve the substrate's surface properties. The Vickers hardness of TiN is 1800-2100, the elastic modulus is 251 GPa, the coefficient of thermal expansion is 9.35×10-6 K-1, and the superconducting transition temperature is 5.6K.


Ti nitride will oxidize at 800°C at normal temperature. TiN coating color is brown and golden. According to laboratory tests, it is chemically stable at 20°C but will be slowly eroded by concentrated acid solutions at high temperatures. Depending on the material and surface finish of the substrate, the friction coefficient between TiN and another TiN is 0.4 to 0.9 TiN surface (unlubricated). The typical TiN formation has a NaCl-type crystal structure with a stoichiometric ratio of about 1:1. However, TiNx compounds with x in the range of 0.6 to 1.2 are thermodynamically stable.


TiN becomes superconducting at low temperatures; for single crystals, the critical temperature is as high as 6.0K. The superconductivity in thin-film TiN has been extensively studied, and its superconductivity varies greatly depending on the sample preparation until the superconductivity in the superconductor-insulator transition is completely suppressed. Cooling the TiN film to an absolute value close to zero, converting it into the first known super insulator, suddenly increased the resistance by 100,000 times.


Titanium nitride coating: TiN is a hard ceramic material used as a coating on titanium alloys, steel, carbides, and aluminum parts. Because of its golden surface, it can be used for jewelry, high-performance ceramic materials, and medical equipment such as scalpels, plastic bone, and saw blades. In addition, it is also used as a conductive barrier in microelectronics and electrodes in bioelectronic applications.

 How is Titanium Nitride TiN Powder produced? 

Titanium nitride can be made by directly reacting titanium and nitrogen at 1200°C. The coating can be formed by a vapor deposition method using a mixed gas of titanium tetrachloride, nitrogen, and hydrogen. Titanium dinitride is obtained by heating metallic titanium in nitrogen or ammonia at 900-1000°C. Titanium tetranitride is obtained by heating titanium tetrachloride in ammonia at 1000°C.

Product Performance of Titanium Nitride TiN powder:
Our Titanium Nitride, TiN powder (CAS 25583-20-4) has high purity, narrow size distribution, high temperature strength, high fracture strength, good chemical resistance, good thermal shock resistance, low density and high hardness.

Characteristics of titanium nitride TiN powder:

High melting point and hardness: Titanium nitride has a melting point of 3050°C and a very high hardness, second only to diamond and cubic boron nitride. This high hardness and melting point give titanium nitride great potential for high-temperature and high-strength applications.

Good chemical stability: Titanium nitride is highly resistant to most chemicals at room temperature, including strong acids, bases, and oxidizing agents. This stability allows titanium nitride to have various applications in the chemical industry and laboratory equipment.

Good Thermal Conductivity and Resistivity: Titanium nitride has very good thermal conductivity, higher than copper, but lower electrical conductivity. This gives Titanium Nitride an advantage in applications where high thermal conductivity is required but not high electrical conductivity, such as heat sinks, heat shielding, and electronic packaging.

Biocompatibility: Titanium nitride powders are biocompatible with the human body and can be used in biomedical applications such as dental and orthopedic implants.

Magnetic: Some titanium nitride alloys are ferromagnetic, which makes them potentially useful in magnetic storage and electronic devices.

Applications for titanium nitride powders

Coatings and coated tools:

Due to their high hardness and chemical stability, titanium nitride powders are widely used as hard coatings and coated tools. For example, coating cutting tools such as knives and drills with titanium nitride can improve the wear resistance and life of the tools. In addition, titanium nitride coatings can prevent tools from rusting during machining.

Electronic packaging materials:

Due to its high thermal conductivity and chemical stability, titanium nitride is widely used in electronic packaging. Especially in high-power electronic equipment, titanium nitride can effectively solve problems caused by heat accumulation and improve the reliability and stability of the equipment.

Wear-resistant coating:

The high hardness and chemical stability of titanium nitride make it an excellent material for wear-resistant coatings. This coating can be applied to various sliding and friction components, such as engine and turbine blades, to improve their wear resistance and life.

Biomedical Applications:

Titanium nitride is widely used in biomedical applications due to its excellent biocompatibility. In dentistry, titanium nitride is used to make dental implants that are similar in color to natural teeth, improving the aesthetics and comfort of the implants. In orthopedics, titanium nitride is also used to make artificial joints and bone plates to improve the body's tolerance to implants.

Optical coatings:

Titanium nitride has a high light transmission and refractive index, making it an ideal material for optical coatings. Coating the surface of an optical element with titanium nitride reduces reflections and increases light transmission, thereby improving the performance of the optical system.

Magnetic Materials:

Titanium nitride alloys with ferromagnetic properties can make magnetic storage materials and components in electronic devices.

High-temperature structural materials: 

Due to its high melting point and hardness, titanium nitride can perform excellently in high-temperature environments. For example, in the aerospace and automotive industries, titanium nitride can be used to make high-temperature turbines and combustion chamber components.
