What is titanium carbide powder? Titanium carbide powder, density 4.93g/cm3, melting point 3140 ° C, boiling point 4300 ℃, CAS No. 12070-08-5, molecular formula TiC, gray-black powder. It has a NaCl cubic crystal structure. Due to its high melting point, high hardness, and good chemical stability, it is mainly used to manufacture cermets, heat-resistant alloys and hard alloys. Titanium carbide can form binary, ternary, and quaternary compound solid solution with tungsten carbide, tantalum carbide, niobium carbide, chromium carbide, and titanium nitride, and is used for spraying materials and welding materials, Hard film materials, military aviation materials, hard alloys and cermets. TiC has high melting point, high conductivity, low coefficient of thermal expansion, high hardness, and excellent oxidation resistance and chemical stability.
Use of titanium carbide powder Titanium carbide powder is applied to high-temperature thermal spraying materials, welding materials, hard film materials, military aviation materials, cemented carbide and cermets. Adding 6-30% titanium carbide powder to tungsten carbide - cobalt series cemented carbide can form titanium carbide - tungsten carbide solid solution, which can improve the hardness, wear resistance, oxidation resistance and corrosion resistance of the alloy. It is more suitable for processing steel than WC-Co cemented carbide, and is widely used in cemented carbide cutting tool products; It is applied to Ni-Mo and other alloys as binder to make tungsten free cemented carbide, which can improve the turning speed and the precision and finish of machined parts. It is used as an additive to make thermistors and improve wear resistance.
Preparation of titanium carbide powder Direct carbonization of titanium metal powder or TiH2 powder is a traditional method for preparing TiC. The process is to use sodium to reduce spongy titanium powder or titanium powder (particle size at least 5 μ The mixture of titanium powder and carbon black (the carbon content of the mixture is 5%~10% more than the theoretical content, and it is dry-mixed by a ball mill) is formed at a pressure of about 100 MPa. Then it is put into a graphite container, and heated to 1500~1700 ℃ in a high-purity (dew point is below - 35 ℃) air stream using a carbonization induction heating furnace. The reaction temperature and holding time are determined by factors such as the type of raw material, particle size and reaction performance, Especially, the titanium powder obtained by decomposition of titanium hydride has strong activity. It is easy to obtain titanium carbide with a theoretical carbon content (20.05%) at 1500 ℃ for 1 h.
Price of titanium carbide powder Titanium carbide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of titanium carbide powder. A large amount of large amount will be lower. The price of titanium carbide powder can be found on our company's official website.
