What is titanium nitride powder? Titanium nitride powderhas a typical NaCl-type structure belonging to the face-centred cubic lattice. The top of the face-centred cubic is a nitrogen atom, and the titanium atom is located in the (1/2,0,0) space position of the face-centred cubic. TiN is a non-stoichiometric compound, and its stable composition range is TiN0.6~TiN1.16. The nitrogen content can change within a certain range without causing changes in the structure of TiN. The tiN powder is generally yellowish brown, the ultrafine TiN powder is black, and the TiN crystal is golden yellow. The lattice constant of TiN is a=4.23 nm, The lattice constant of TiC is a=4.238 nm, and the lattice constant of TiO is a=4.15 nm. The lattice parameters of these three substances are very close, so the nitrogen atoms in TiN molecules can be replaced by oxygen and carbon atoms in any ratio to form a solid solution. The nitrogen element's content determines titanium nitride's physical and chemical properties. When the nitrogen element's content decreases, titanium nitride's lattice parameters will increase, and the hardness will also increase slightly. Still, the seismic resistance of titanium nitride will decrease.
Application of titanium nitride powder Titanium nitride is a new type of multifunctional ceramic material. Adding a certain amount of titanium nitride to TiC-Mo-Ni series cermets will significantly refine the hard phase grains, thus greatly improving the physical and chemical properties of ceramics, both at room temperature and high temperature and then greatly improving the high-temperature corrosion resistance and oxidation resistance of cermets; Adding TiN powder to ceramics in a certain proportion can enhance the strength, toughness and hardness of ceramics; Nano-titanium nitride is added to TiN/Al2O3 composite nano-ceramics and mixed evenly by various methods (such as mechanical mixing method). The ceramic material containing nano-titanium nitride particles will form a conductive network inside. This material can be used as electronic components in the semiconductor industry.
Preparation of titanium nitride powder The chemical vapour deposition method uses gaseous TiCl4 as raw material, H2 as a reducing agent and N2 to produce TiN, and the synthesis temperature is 1100~1500 ℃. This process is often used to coat metal and ceramic surfaces to enhance the hardness and wear resistance of ceramics and metals. This synthetic TiN has high purity but low production efficiency and high cost. This process is a common method for coating TiN films on the surface of metals, ceramics and other articles to make them beautiful.
Price of titanium nitride powder Titanium nitride powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of titanium nitride powder. A large amount of large amount will be lower. The Price of titanium nitride powder can be found on our company's official website.
