What is titanium diboride?
Titanium diboride powder is gray or grayish black with a hexagonal (AlB2) crystal structure. Its melting point is 2980 ℃, with high hardness. The oxidation resistance temperature of titanium diboride in the air can reach 1000 ℃, and it is stable in HCl and HF acids. Titanium diboride is mainly used to prepare composite ceramic products. Due to its resistance to molten metal corrosion, it can be used to manufacture molten metal crucibles and electrolytic cell electrodes.
Composition and structure of titanium diboride
Titanium boride (TiB2) is the most stable compound of boron and titanium, with a C32-type structure. It is bound in the form of its valence bond and belongs to a hexagonal system of quasi-metallic compounds. The structural parameters of its complete crystal are a=0.3028 nm and C=0.3228 nm. The crystal structure's boron and titanium atomic surfaces alternately form a two-dimensional network structure. B and the other 3 B are covalently bonded, and the remaining electron forms a large π bond. This layered structure of boron atoms is similar to graphite, and the outer electrons of Ti determine that TiB2 has good electrical conductivity and metallic luster. In contrast, the Ti-B bond between the boron and titanium atomic surfaces determines this material's high hardness and brittleness.
Application fields of titanium diboride
Conductive ceramic materials. It is one of the primary raw materials for vacuum coating conductive evaporation boats. Ceramic cutting tools and molds. Can manufacture precision machining tools, wire drawing molds, extrusion molds, sandblasting nozzles, sealing components, etc. Composite ceramic materials. It can be used as an essential component of multicomponent composite materials to form composite materials with TiC, TiN, SiC, and other materials, making 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—cathodic coating material for aluminum electrolytic cells. Due to the excellent wettability of TiB2 with molten aluminum, using TiB2 as a cathode coating material for aluminum electrolytic cells can reduce the power consumption of the cells and prolong their life of the cells. Made into PTC heating ceramic and flexible PTC materials, it is characterized by safety, power saving, reliability, and easy processing and molding. It is an updated high-tech product of various types of electric heating materials. It is a good strengthening agent for metal materials such as Al, Fe, and Cu.
