What is titanium nitride? Physical properties of titanium nitride: melting point 2950.6~3205.8 ℃, linear expansion coefficient 5.712~7.053 × 106 (1/K) (25 ℃), density 5.435~5.447 g/cm3, thermal conductivity 25.081 (W · m-1 · K-1) (300~2000 ℃), Mohs hardness 8~9. Generally, the colour of titanium nitride powder is taupe, the colour of black is ultra-fine titanium nitride powder, the colour of yellow is titanium nitride crystal, and a large number of titanium nitride crystals have a golden metallic lustre. The chemical property of titanium nitride: is relatively stable and does not react with water and acid (hydrochloric acid and sulfuric acid); however, it can be mixed with hydrofluoric acid. If the hydrofluoric acid contains an oxidant, titanium nitride will be completely dissolved in hydrofluoric acid. When titanium nitride is dissolved in a strong alkali solution, it decomposes and releases ammonia.
Use of titanium nitride The pollution method limits the use of bromine and benzene-containing polymers, which complicates the electronic flame retardant and plastic shell skeleton. Suppose a small amount of silicon nitride, silicon carbide, titanium nitride, titanium carbide and other nano-powders are added to the engineering plastics. In that case, it will not only increase the mechanical strength, wear resistance, heat resistance and other properties but also make a great breakthrough in the application of organic polymers if it can replace the performance of bromine-containing flame retardant materials; Applications in other fields: in nanocomposite hard tools, hard alloys, high-temperature ceramic conductive materials, heat-resistant and wear-resistant materials, dispersion strengthening materials, etc., and also in electrode catalysts, anti-static materials and conductive ceramics of fuel cells.
Synthesis of titanium nitride The mechanical alloying method is to put titanium powder in the system of ammonia or nitrogen and use a high-energy ball mill to make them interact with each other under the strong impact and agitation of the grinding ball to obtain nanometer titanium nitride. This is a new method of synthesis. In China, Liu Zhijian and others used TiH1.924 powder to replace Ti powder and react with nitrogen. Using this high-energy ball milling process, after 100 hours of high-energy ball milling in flowing ammonia, almost all TiH1.924 was converted into TiN. The conversion rate was greatly improved, and Zhou Li and others later prepared nano-titanium nitride powder by the same method, and the reaction time was only nine h.
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.
