The titanium diboride powder is gray or gray-black and has a hexagonal (AlB2) crystal structure. The melting point of titanium diboride is 2980°C, and it has a very high hardness. The anti-oxidation temperature of titanium diboride in the air can reach 1000℃, and it is stable in HCl and HF acid.
Titanium Diboride Powder Properties
Titanium diboride (TiB2) is the most stable compound of boron and titanium. It has a C32 structure and is combined in the form of valence bonds. It is a metalloid compound of the hexagonal crystal system. The structural parameters of the complete crystal are: a is 0.3028nm, and C is 0.3228nm.
In the crystal structure, the boron atom plane and the titanium atom plane alternately form a two-dimensional network structure, in which B is covalently bonded with the other three Bs, and an extra electron forms a large π bond. This graphite-like layered structure of boron atoms and Ti outer layer electrons determine the good conductivity and metallic luster of TiB2, and the Ti-B bond between the boron atomic surface and the titanium atomic surface determines the high hardness of this material And brittleness.
Titanium Diboride Powder Applications
Titanium diboride is mainly used to prepare composite ceramic products. Because of its resistance to molten metal corrosion, it can be used in the manufacture of molten metal crucibles and electrolytic cell electrodes.
1. Conductive ceramic materials. Titanium diboride is one of the main raw materials for the vacuum coating conductive evaporation boat.
2. Ceramic cutting tools and molds. Titanium diboride can be used to manufacture finishing tools, wire drawing dies, extrusion dies, sandblasting nozzles, sealing elements, etc.
3. Composite ceramic materials. Titanium diboride can be used as an important component of multiple composite materials. It can be combined with TiC, TiN, SiC and other materials to form composite materials to make various high temperature resistant parts and functional parts, such as high temperature crucibles, engine parts, etc. It is also a material for making armor protection. One of the best materials.
4. Cathode coating material for aluminum electrolytic cell. Due to the good wettability of TiB2 and metal aluminum liquid, using TiB2 as the cathode coating material of the aluminum electrolytic cell can reduce the power consumption of the aluminum electrolytic cell and prolong the life of the electrolytic cell.
5. Titanium diboride can be made into PTC heating ceramic materials and flexible PTC materials. It has the characteristics of safety, power saving, reliability, and easy processing and molding. It is an updated high-tech product of various electric heating materials.
6. Titanium diboride is a good strengthening agent for Al, Fe, Cu and other metal materials.
