Titanium borate (TiB2) is the most stable compound of boron and titanium. It is a C32 structure, which is bound in the form of a valence bond. It is a quasi-metallic compound of a hexagonal system. The structural parameters of the complete crystal are: A is 0.3028nm, and C is 0.3228nm. In the crystal structure, the boron atomic plane and titanium atomic plane alternate to form a two-dimensional network structure, in which B is combined with the other three B by covalent bonds, and the extra electron forms a large π bond. The layered structure of boron atoms similar to graphite and the electrons in the outer layer of Ti determine that TiB2 has good conductivity and metallic luster, and the Ti-B bond between boron and titanium atomic planes determines the high hardness and brittleness of this material.
Titanium diboride powder (TiB2) is the most stable compound of boron and titanium, with unique physical and chemical properties such as high melting point, high hardness, good conductivity, oxidation resistance, corrosion resistance, and good wettability with metals. These characteristics make titanium diboride widely used in many fields, and all of its main applications will be described in detail below.
High temperature structural materials field

Adding an appropriate amount of titanium diboride powder to aluminum alloys can effectively refine their grain structure, improve their strength, hardness, and toughness.
This is because titanium diboride particles can serve as heterogeneous nucleation cores during the solidification process of aluminum alloys, promoting grain refinement. Meanwhile, titanium diboride particles can also hinder the movement of dislocations, improving the yield strength and tensile strength of the material. In copper based and iron-based materials, titanium diboride also has a similar strengthening effect, which can significantly improve the performance of the material and meet the needs of different engineering applications.
Titanium diboride can be used as an important component in multicomponent composite materials, and can be combined with non oxide ceramics such as TiC, TiN, SiC, as well as oxide ceramic materials such as Al ₂ O3. Through compounding, new composite materials have higher mechanical strength and fracture toughness.
For example, the composite material prepared by combining titanium diboride with silicon carbide combines the advantages of both materials, possessing both the high hardness and good conductivity of titanium diboride and the high strength and high temperature resistance of silicon carbide. This composite material can be used to make various high-temperature resistant components and functional parts, such as high-temperature crucibles, engine components, etc. In aerospace engines, components made of this composite material can withstand higher temperatures and pressures, improving engine performance and reliability.
In recent years, with the deepening of research on armor protection, ceramic composite armor has gradually replaced thick homogeneous armor and become the focus of research in the field of armor protection. Ceramic materials have also become an indispensable material for composite armor. Titanium diboride ceramics have excellent mechanical properties such as high strength, high hardness, and low density, and have important applications in armor protection.
It can be combined with other ceramic or metal materials to prepare high-performance armor protection materials. When impacted by a projectile, titanium diboride ceramics can effectively absorb and disperse the energy of the projectile, reducing damage to personnel and equipment inside the armor. At the same time, its low-density characteristics also help reduce the weight of armor and improve the maneuverability of armored vehicles.

Titanium diboride (TiB2), as a high-performance ceramic material, has various production methods, including the following:
Titanium dioxide (TiO2) and boron carbide (B4C) are used as raw materials to generate titanium diboride through solid-state reaction at high temperature. The reaction equation is: 2TiO2 +B4C+3C→2TiB2 +4CO↑
This method has low raw stuff cost and simple process, but the reaction temperature is high (usually exceeding 1600 ℃), which easily generates toxic gases such as carbon monoxide, and the particle size is large, requiring subsequent treatment to optimize performance.
Using titanium tetrachloride (TiCl4) and boron trichloride (BCl3) as raw stuffs, titanium diboride is generated through chemical vapor deposition reaction at high temperatures of 800-1000 ℃ with the participation of hydrogen gas (H2).
The reaction equation is: TiCl4+2BCl3 +5H2 →TiB2 +10HCl↑
This method can prepare high-purity, fine-grained titanium diboride powder or coating, suitable for electronic and abrasive grade products, but the equipment cost is high and the process control is complex.
Directly mixing titanium powder (Ti) and boron powder (B), a chemical reaction occurs at high temperatures (usually exceeding 2000 ℃) to produce titanium diboride. The reaction equation is: Ti+2B→TiB2
This method has high product purity, but the reaction temperature is extremely high, the raw stuff cost is high, and titanium boride by-products (such as TiB, Ti3B4) are easily generated, requiring strict control of process conditions.
The exothermic reaction of raw stuffs such as titanium powder, boron powder, and magnesium powder is utilized to initiate self propagating combustion synthesis of titanium diboride at local high temperatures. The reaction equation is: TiO2 +5Mg+B2O3 →TiB2 +5MgO
This method has a fast reaction speed and low energy consumption, but there may be residual magnesium oxide in the product, which requires subsequent purification treatment.
Through the hydrolysis and polycondensation reaction of metal alkoxides (such as tetrabutyl titanate) and boron compounds (such as boric acid), a sol gel precursor is formed, and then titanium diboride is generated after high-temperature heat treatment. This method can prepare nanoscale titanium diboride powder, but the raw stuff cost is high and the process cycle is long.
Directly mixing titanium powder (Ti) and boron powder (B), a chemical reaction occurs at high temperatures (usually exceeding 2000 ℃) to produce titanium diboride. The reaction equation is: Ti+2B→TiB2
This method has high product purity, but the reaction temperature is extremely high, the raw stuff cost is high, and titanium boride by-products (such as TiB, Ti3B4) are easily generated, requiring strict control of process conditions.
A new method developed by Tomsk University of Technology in Russia utilizes titanium powder and amorphous boron powder to directly react under an electric arc to produce high-purity titanium diboride. The carbon monoxide in the reaction zone is self shielded, eliminating the need for vacuum equipment, simplifying reactor design, reducing costs, and achieving high product purity.
