Titanium Boride Properties

About Titanium Diboride TiB2 Powder:

Titanium diboride or titanium boride powder is gray or gray-black and has a hexagonal (AlB2) crystal structure. Titanium diboride melting point is 2980°C, and it has 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 is mainly used to prepare composite ceramic products. Because of its resistance to molten metal corrosion, it can be used to manufacture molten metal crucibles and electrolytic cell electrodes.

Titanium diboride TiB2 is an extremely hard ceramic with excellent mutation, oxidation stability, and wear resistance. Titanium diboride (TiB2) is an extremely hard ceramic used, for example, in special ballistic armor applications. In addition, unlike most ceramic components, it is conductive. It is also a reasonable electrical conductor, so it can use the conduit material in aluminum smelting and can be formed by electrical discharge machining.

Titanium diboride (TiB2) is a ceramic material with high strength and hardness, and its melting point, hardness, strength-to-density ratio, and wear resistance are relatively high. However, the current use of this material is probably only in the anti-evolving important application of TiB2 waveguides in the electrochemical reduction of alumina to aluminum metal. If electrical discharge machining of TiB2 is performed, other applications may develop rapidly. It can be perfected. The wide application of this material may be restricted by economic factors, especially the cost of densifying high melting point materials and the reduction in material performance changes.

How is Titanium Diboride TiB2 Powder produced?

Titanium Diboride TiB2 is the most stable of several titanium boron compounds. This material does not appear in nature, but it can be synthesized by carbothermal reduction of TiO2 and B2O3. Like most other covalently bonded materials, TiB2 is resistant to sintering and is usually compacted by hot or hot isostatic pressing. Pressureless sintering of TiB2 can achieve high density but requires liquid sintering aids such as iron, chromium, and carbon.

TiB2 does not naturally exist on the earth. Titanium diboride powder can be prepared using high-temperature methods, such as direct reaction to prepare titanium or its oxide/hydride. When elemental boron exceeds 1000°C, carbothermal reduction by thermite reaction has been developed in various synthesis pathways. Electrochemical synthesis and solid-state reaction prepared more refined titanium diboride in large quantities.

Application of Titanium Diboride TiB2 Powder:

Titanium Diboride (TiB2) is a hard material with high strength and wear resistance at elevated temperatures. The high density, elastic modulus, and compressive strength have led to its use in armor components.

It is unaffected by most chemical reagents and has excellent stability and wettability in liquid metals such as zinc and aluminum. This, along with its high electric conductivity, has led to its use in Hall- Héroult cells for aluminum production. It is also used as a crucible for molten metals. Due to its high hardness, extremely high melting point, and chemical inertness, TiB2 is a candidate material for many applications.

Ballistic armor

High hardness and medium strength make it attractive for ballistic armor. Still, its relatively high density and difficulty forming shaped parts make it less attractive than some other ceramics.

Aluminum Smelting

The chemical inertness and good conductivity of TiB2 have made it used as a cathode in Hall-Heroult batteries used for primary aluminum smelting. It can also be used as a crucible and metal evaporation boat for processing molten metal.

Other uses

High hardness, medium strength, and good wear resistance make titanium diboride a candidate material for sealing parts, wearing parts, and composite materials with other materials and cutting tools.

Used in combination with other major oxide ceramics, TiB2 is used to form composite materials, where the presence of the material helps increase the strength and fracture toughness of the matrix.

Potential applications of TiB2

The current uses of TiB2 are almost limited to special applications in impact-resistant armor, cutting tools, crucibles, neutron absorbers, and wear-resistant titanium diboride coating.

TiB2 is widely used as a vaporizer for vaporizing aluminum. For the aluminum industry, is a selective material that can be used as an inoculant for grain refinement when casting aluminum alloys because of its implantability, low solubility in molten aluminum, and good electrical conductivity.

TiB2 films can provide wear and corrosion resistance to inexpensive and strong substrates.
