In the Ti-B phase diagram, titanium diboride is a covalently linked transition metal boride with 31.1% Boron (B). Titanium diboride (TiB2) has excellent melting point (2920 °C), hardness (25,5 GPa), electrical and thermal conductivity, and wear and corrosion resistance. Compared to other borides, it has a low density (4.52 g/cm3). Carbothermal reduction, borothermal reduction, metallothermic reduction, sol-gel, self-propagating high-temperature synthesis (SHS), molten salt electrolysis, physical vapor deposition (PVD), and mechanochemical processes etc. are methods for production of TiB2.

The aim of this research is to employ the carbothermal reduction method to create TiB2 by producing precursor material. This technique necessitates the use of titanium, carbon, and boron sources. Sucrose was utilized as the carbon source due to it can totally decompose into carbon and water. Boric acid was also preferred as a boron source. The synthesis process was carried out by mixing TiO2 with the precursor material obtained from boric acid and sucrose. As a result, the production of high-purity TiB2 powders has been achieved.
