The properties and applications of titanium nitride TiN

Titanium nitride TiN overview

Titanium nitride is a compound with a molecular formula of TiN and a molecular weight of 61.88. TiN powder is generally yellowish brown, ultrafine TiN powder is black, and TiN crystals are golden yellow. TiN has a melting point of 2950°C, a Mohs hardness of 8-9, and good thermal shock resistance. The melting point of TiN is higher than that of most transition metal nitrides, but the density is lower than that of most metal nitrides.

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

The properties of titanium nitride TiN

There are two kinds of titanium nitride (Ti2N2) and titanium tetranitride (Ti3N4). Titanium dinitride is a yellow solid. Dissolved in boiling aqua regia. When encountering hot sodium hydroxide solution, ammonia will be released. The properties of titanium tetranitride are similar to those of titanium dinitride.

[Preparation or source] It can be prepared by direct reaction of titanium and nitrogen at 1200℃. 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.

Application of Titanium Nitride TiN

Titanium Nitride (TiN) is a fairly stable compound that will not react with metals such as iron, chromium, calcium, and magnesium at high temperatures. TiN crucible does not react with acidic slag and alkaline slag under CO and N2 atmosphere, so TiN crucible is an excellent container for studying the interaction between molten steel and certain elements. TiN loses nitrogen when heated in a vacuum and produces titanium nitride with a lower nitrogen content.

TiN has an attractive golden color, high melting point, high hardness, good chemical stability, low wettability with metals, high conductivity and superconductivity, and can be used in high-temperature structural materials and superconducting materials

Titanium nitride is a hard ceramic material used for coating titanium alloy, steel, hard alloy and aluminum parts. Because of its golden yellow surface, it can be used in jewelry and high-performance ceramic materials, as well as scalpels and orthopedic bone saw blades and other medical equipment. In addition, it is also used as a conductive barrier for microelectronics and electrodes in bioelectronic applications.

TiN is used as a thin coating to harden and protect cutting and sliding surfaces, for decorative purposes (due to its golden appearance), and as a non-toxic exterior for medical implants. In most applications, the applied coating thickness is less than 5 microns (0.00020 inches). TiN is generally used for steel, hardened steel and stainless steel materials that require high wear resistance and lubricity. TiN is an important material for physical vapor deposition coatings and is very suitable for applications that use expensive tools (such as injection molding, sawing, tapping, and molding).

The coating is also used in many medical (implants, surgical instruments, etc.) and food processing applications. TiN can be easily stripped and recoated. It can be stripped and repainted.

Manufacturing plastic packaging materials, such as PET bottles.

In the solar vacuum tube, the absorbed sunlight is very large.

The high temperature furnace is used for energy consumption.

Make artificial limbs and biological materials.

Manufacturing optical equipment in harsh environments.

Used as alloy modifier in cemented carbide.
