Composition structure of titanium diboride

Titanium boride (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 and the other 3 B are covalently bonded, and the extra electron forms a large π bond. This graphite-like layered structure of boron atoms and Ti outer layer electrons determine that TiB2 has good conductivity and metallic luster, 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 boride (TiB2) is used in a variety of compounds, and metal borides have better high temperature performance than metal carbides. For example, diboride (TiB2) cermet products are more suitable for use under high temperature and corrosive working conditions than titanium carbide (TiC) and tungsten carbide (WC) cermet products. Titanium diboride powder is gray (or gray-black). It ranks sixth among the top ten materials with the highest melting point in the world, and its anti-oxidation temperature in the air can reach 1100°C. As a new type of ceramic material, it has excellent physical and chemical properties. In addition to its high melting point, it has high hardness, chemical stability, electrical and thermal conductivity, and mechanical and mechanical properties at high temperatures. very talented.

Titanium diboride TiB2 powder application

Titanium diboride TiB2 powder is mainly used to prepare composite ceramic products. Due to its ability to resist molten metal corrosion, it can be used to manufacture molten metal crucibles and electrolytic cell electrodes. Titanium diboride (TiB2) is a hard material with high strength and high wear resistance, high density, coupled with high elastic modulus and high compressive strength, so it must be used for armor parts. It is not affected by most chemical reagents, and has excellent stability and wettability in liquid metals such as zinc and aluminum. This extremely high conductivity makes it useful for Hall-Elliott electrolysis cells for the production of aluminum. Due to its high hardness, extremely high melting point and chemical inertness, TiB2 is also used as a crucible for molten metals and is a candidate material for many applications.

Ballistic armor: The combination of high hardness and medium strength makes it attractive to ballistic armor. However, its relatively high density and processing difficulty of molded parts make it less attractive than other ceramics.

Aluminum smelting: The chemical inertness and good conductivity of TiB2 make it the cathode of Hall-Helo battery for primary aluminum smelting. It can also be used as a crucible and metal evaporation boat to process molten metal.

Other uses: high hardness, medium strength and good wear resistance make titanium diboride a candidate material for other materials and tool seals, wearing parts and composite materials. TiB2 combines with other main oxide ceramics to form composite materials, where the presence of the material helps to improve the strength and fracture toughness of the matrix.

At present, the use of titanium diboride TiB2 is almost limited to special applications in the fields of impact-resistant armor, cutting tools, crucibles, neutron absorbers, and wear-resistant coatings.

Titanium diboride TiB2 is widely used as a vaporizing agent for vaporizing aluminum. In the aluminum industry, due to its implantability, low solubility in molten aluminum, and good electrical conductivity, it is a selective material that can be used to cast aluminum alloy as an inoculant for grain refinement.

The TiB 2 film of titanium diboride can be used to provide the TiB 2 of titanium diboride powder with low cost or strong substrates.The dispersibility and use effect of wear resistance and corrosion resistance. Therefore, TiB 2 of titanium diboride powder should be sealed and stored in a cool and dry room in a vacuum package. Titanium diboride TiB2 powder should not be exposed to the air. In addition, avoid using titanium diboride TiB2 powder under pressure.
