Titanium Diboride (TiB2) Micron Powder

What is Titanium diboride?

A hot pressing process prepared titanium diboride (TiB2) and its ceramic composites. The sintering process, phase evolution, microstructure, and mechanical properties of TiB2 ceramics prepared by using different milling media materials: tungsten carbide (WC/Co) or SiAlON was studied. It was found that the inclusion of WC/Co significantly improved the sinterability of the TiB2 ceramics. A core/rim structure was identified with pure TiB2 as the core and W-rich TiB2, i.e., (Ti, W)B2 as the rim. Microstructure analysis revealed that this core/rim structure was formed through a dissolution and re-precipitation process. In addition, silicon carbide (SiC) was also introduced to form TiB2–SiC composites. The addition of SiC as the second phase not only improved the sinterability but also led to greatly enhanced fracture toughness. The optimum mechanical properties with Vickers hardness ~ 22 GPa, and fracture toughness ~ 6 MPa m1/2 were obtained on TiB2–SiC composites milled with WC/Co.

 

Titanium Diboride (TiB2) Micron Powder

Titanium diboride (TiB2) is an extremely hard ceramic with excellent heat conductivity, oxidation stability, and resistance to mechanical erosion. Its melting point is approximately 3230, and its density is 4.52 g/cm3. Titanium Boride is the most stable of several titanium-boron compounds. The material does not occur in nature but may be synthesized by carbothermal reduction of TiO2 and B2O3. TiB2 is resistant to oxidation in air at temperatures up to 1100 °C and hydrochloric and hydrofluoric acids but reacts with alkalis, nitric acid, and sulfuric acid. TiB2 is also a reasonable electrical conductor, so it can be used as a cathode material in aluminum smelting and can be shaped by electrical discharge machining. Titanium boride micron powders are commonly used in ceramic sintered parts and structural applications, including cutting tool composites, ceramic armor nozzles, wear parts, seals, molten metal crucibles, and metalizing boats.

 

Aqueous dispersions of highly luminescent boron-rich nanosheets by the exfoliation of polycrystalline titanium diboride

Titanium diboride (TiB2) is a layered inorganic material composed of graphene boron sheets alternating with titanium cations. Here we report bulk titanium diboride (TiB2) exfoliation to yield aqueous dispersions of two-dimensional (2D), boron-rich nanosheets. The delamination was realized by subjecting the pristine material to repeated cycles of shear-force grinding in an aqueous medium followed by ultrasonication. The physicochemical characterization of the nanosheets has registered a significant decrease in the titanium-to-boron atomic ratio (i.e., with boron-rich stoichiometry) compared to the pristine material. The aqueous dispersed boron-rich nanosheets were highly photoluminescent with a quantum yield of about 13%, unlike the pristine material, which has no luminescence traits. This is the first successful exfoliation of a 2D material realized from bulk polycrystalline TiB2. The synthesis of stable, water-dispersible nanosheets with a high boron-to-titanium ratio may be an important step in the journey of 2D, boron-based nanosheet fabrication.
