What is titanium nitride powder? Titanium nitride is an excellent structural material for high-strength metal-ceramic tools, steam injection thrusters, and rockets. In addition, titanium nitride has a low friction coefficient and can be used as a high-temperature lubricant. Titanium nitride alloy can show excellent effects as a bearing and sealing ring. Titanium nitride has high conductivity and can be used as an electrode and point contact for molten salt electrolysis, Thin film resistance and other materials. Titanium nitride has a high superconducting critical temperature, an excellent superconducting material. Especially remarkable is that titanium nitride coating and its sintered body have a satisfactory golden colour, which can be used as a gold substitute decorative material with a good gold-like effect, decorative value and anti-corrosion; it extends the life of handicrafts. The glass coated with titanium nitride film is a new "thermal mirror material". When the thickness of the film is greater than 90 nm, the infrared reflectance is greater than 75, which improves the thermal insulation performance of the glass. The colour of the titanium nitride film can also be adjusted at will. With the reduction of nitrogen content, the film will appear golden and bronze; Pink and other colours are very beautiful. The demand for titanium nitride powder has increased sharply due to the development of nitrogen-containing cermet tools, and the development of gold substitute decoration technology in the world is quite fast. The application of titanium nitride in this field has a very broad prospect. Not only because of the low price of titanium nitride coating but also because it is superior to vacuum coating in corrosion resistance, friction resistance and other properties. Therefore, the research on titanium nitride has important economic significance.
Use of titanium nitride For example, in the development of lead-free solder materials, a small amount of titanium nitride nano-powder is added into tin, silver, copper, zinc, and other alloys to reduce the melting temperature by 200 ℃, to produce more uniform alloys, and to reduce the temperature of solid oxide solution by 30 ℃, which can not only reach the original use temperature of lead-free solder but also solve the application difficulty of existing lead-free solder if the wettability can be further improved.
Preparation of titanium nitride The carbothermal reduction and nitridation method of TiO2 takes TiO2 as raw material and carbonaceous graphite as a reducing agent and reacts with N2 to generate TiN. The synthesis temperature is 1380~1800 ℃, and the reaction time is about 15h. In this reaction environment, carbon reacts with oxygen and titanium to generate TiC because the lattice of titanium carbide, titanium nitride and titanium oxide are very close, and the three are easy to form a solid solution. The TiN obtained by this method is generally not high in purity, and the content of O and C is relatively high. To obtain O, TiN with low C content needs a higher reaction temperature and longer reaction time. In addition, some experts have adopted another method, namely, preparing titanium nitride by mixing magnesium powder and titanium oxide at a certain proportion at a lower temperature.
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.
