What is titanium nitride powder? Titanium nitride powder has 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.
Synthesis of titanium nitride powder 1. Molten salt synthesis method: There is no relevant report on the preparation of titanium nitride, but the research on the preparation of titanium nitride by this method is a good research direction. This method uses molten salt with a low melting point as the reaction medium, and the reactants can be dissolved in the molten salt. The whole reaction is completed in the atomic-level environment. After the reaction, the salt is dissolved in a suitable solvent; The product can be obtained by filtration. The product obtained by this method has high purity, simple operation, short reaction time, and no strict requirements on the reaction temperature. The morphology and particle size of the product can be easily controlled without agglomeration 2. Sol-gel method: Sol-gel mixes the reactants evenly in the liquid phase, then condenses. The reactants will form transparent sol in the solution. This sol will form a gel after ageing and slow polymerization. The gel will be dried and solidified to get the materials we need. Some organic solvents used in this method in the operation process are toxic and harmful to the human body.
Main uses of titanium nitride powder: 1. It is used for manufacturing cemented carbide, cutting tools, moulds, melting metal crucibles, etc., and is used for wear resistance and high-temperature resistance 2. Used as wear-resistant and corrosion-resistant coating on the surface of materials, such as depositing a TiN coating on cutting tools, can greatly improve the wear resistance of cutting tools and prolong the service life of cutting tools 3. As a high-temperature lubricant, it has a low friction coefficient and can be used as a bearing and sealing ring 4. As a conductive material, electrodes, electrical connectors, film resistors, etc., used for molten salt electrolysis have good conductivity 5. It can be used as imitation gold material in the jewellery industry and decoration industry, which is beautiful and can prevent corrosion and prolong the life of handicrafts.
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.
