Titanium nitride is known as TiN powder, the melting point is higher than that of most transition metal nitrides, but the density is lower than most metal nitrides, so it is a heat-resistant material. Purity: 99.5%
Particle Size: 1-3um
About 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 surface properties of the substrate. The Vickers hardness of TiN is 1800-2100, the elastic modulus is 251 GPa, the coefficient of thermal expansion is 9.35x10-6 K-1, and the superconducting transition temperature is 5.6K.
Ti nitride will oxidize at 800degC at normal temperature. TiN coating color is brown and golden. According to laboratory tests, it is chemically stable at a temperature of 20degC but will be slowly corroded 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, and 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 and high-performance ceramic materials, as well as medical equipment such as scalpels and plastic bone, 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 1200degC. 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 900-1000degC. Titanium tetranitride is obtained by heating titanium tetrachloride in ammonia at 1000degC.
