What is titanium diboride?
Titanium diboride powder is gray or black with a hexagonal (AlB2) crystal structure. Its melting point is 2980 , with high hardness. Titanium boride (TiB2) is the most stable compound of boron and titanium. It is a C32-type structure, bound in the form of its valence bond, and belongs to a quasi-metal combination of a hexagonal crystal system. The structural parameters of its complete crystal are: a is 0.3028 nm, and C is 0.3228 nm. In the crystal structure, the boron atomic plane and the titanium atomic plane alternately appear to form a two-dimensional network structure. B and the other three B are covalently bonded, and the extra one electron forms a large π bond. The layered structure of boron atoms similar to graphite and the outer electrons of Ti determine that TiB2 has good conductivity and metallic luster. In contrast, the Ti-B bond between the boron atomic plane and the titanium atomic plane determines this material's high hardness and brittleness.

Role of titanium diboride
First, the conductive ceramic material is one of the primary raw materials of the vacuum coating conductive evaporation boat. Second, ceramic cutting tools and molds can manufacture finishing tools, and wire drawing dies, extrusion dies, sandblasting nozzles, sealing elements, etc. In addition, composite ceramic materials can be used It can be used as an essential component of multi-component composite materials to form composite materials with TiC, TiN, SiC, and other materials to make various high-temperature resistant components and functional components, such as high-temperature crucibles, engine components, etc. It is also one of the best materials for making armor protection materials. In addition, the cathode coating materials for aluminum electrolytic cells Because of the excellent wettability between TiB2 and molten aluminum, using TiB2 as the cathode coating material of aluminum reduction cells can reduce the power consumption of aluminum reduction cells and prolong the cell life. The most important thing is to make PTC heating ceramic materials and flexible PTC materials, which are safe, power-saving, reliable, easy to process and shape, and a new generation of high-tech products for various heating materials. It is an excellent strengthening agent for Al, Fe, Cu, and other metal materials.
Preparation of titanium diboride at high temperature and high pressure
The method for preparing titanium diboride at high temperatures and pressure belongs to the technical field of designing superhard ceramic materials. The titanium diboride material is crafted from titanium powder and boron powder or titanium powder and carbon tetraborate powder through the process of mixing, pressing, assembling, high temperature and high-pressure synthesis, cooling, and pressure relief; On a high-pressure device, the TiB2 bulk sinter was prepared by holding the temperature for 1-3 hours at a pressure of 1.0-6.0GPa and a temperature of 1300 "2000K, then cooling and depressurizing The method of the invention is simple and easy to implement: no flux is used: pure TIB2 material is prepared by changing the ratio of raw materials and synthesis conditions, and the product is pure TB2 phase through X-ray detection, without introducing other impurities.
Price of titanium diboride
The price of titanium boron diboride is generally different with different purity and particle size, and the purchase volume can also affect the cost of titanium diboride. A large amount of large amount will be lower. The price of titanium diboride can be found on our company's official website.
