What is Titanium Diboride used for?

wallpapers News 2021-12-20
Titanium Diboride (TiB2) is a hard material with high strength and high wear resistance at elevated temperatures. The high density, combined with the high elastic modulus and high compressive strength, has to lead 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 crucibles 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
The combination of high hardness and medium strength makes it attractive for ballistic armor, but its relatively high density and difficulty in forming shaped parts make it less attractive than some other ceramics.
Aluminum Smelting
The chemical inertness and good conductivity of Titanium Diboride 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 the fields of impact-resistant armor, cutting tools, crucibles, neutron absorbers and wear-resistant coatings.
TiB2 is widely used as a vaporizer for vaporizing aluminum. For the aluminum industry, it 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 be used to provide wear and corrosion resistance to inexpensive and/or strong substrates.
