Bulk titanium borides (TiB2) have been successfully synthesized from the stoichiometric boron and titanium powders at high pressure and high temperature (HPHT). The density of TiB2 is higher than 99%. The Vicker's hardness of TiB2 as synthesized is 39.6 GPa which is near to result of the supehard materials. While TiB2 show good metallic characters with the resistivity, 10-8 Ωm, which is near to the value of the single crystal of TiB2. The enhanced properties of TiB2 as synthesized may be attributed to the higher density and uniform crystal size.
