Production of TIB2

TiB2 does not occur naturally on Earth. Titanium diboride powders are produced by various high-temperature methods, such as direct reaction of titanium or its oxides/hydrides with elemental boron above 1000°C, carbothermal reduction by the thermite reaction of titanium oxide with boron oxide, or hydrogen. We can manufacture. Reduction of boron halides in the presence of metals or their halides. Electrochemical synthesis and solid-state reactions have been developed among various synthetic routes to prepare larger amounts of finer titanium diboride. An example of a solid-state reaction is borothermal reduction, which the following reaction can illustrate. (1) 2TiO2 + B4C + 3C → 2TiB2 + 4CO (2) TiO2 + 3NaBH4 → TiB2 + 2Na + NaBO2 + 6H2 However, the first synthetic route (1) cannot produce nano-sized powders. Nanocrystalline (5–100 nm) TiB2 was synthesized using reaction (2) or the following technique. Liquid phase reaction of NaBH4 and TiCl4 followed by annealing of the resulting amorphous precursor at 900-1100 °C. Mechanical alloying of a mixture of elemental Ti or B powders. Self-propagating high-temperature synthesis process with varying amounts of NaCl addition. Milling-assisted self-propagating high-temperature synthesis (MA-SHS). Solvothermal reaction of metallic sodium with amorphous boron powder and TiCl4 in benzene at 400 °C: TiCl4 + 2 B + 4 Na → TiB2 + 4 NaCl. The densification cost of the material hampers it. It has a melting point of about 2970 °C and is very resistant to sintering thanks to a layer of titanium dioxide that forms on the surface of the powder particles. Mixing about 10% silicon nitride facilitates sintering, but sintering without silicon nitride has also been demonstrated. Several techniques can produce thin films of TiB2. Electroplating the TiB2 layer has two main advantages compared to physical or chemical vapor deposition. First, the layer growth rate is 200 times faster (up to 5 μm/s), dramatically reducing the inconvenience of covering products with complex geometries.
