Fine particles of TiB2 were prepared by metallothermic reduction (MTR) of TiO2 with Mg or MgO, where we examined the synthesis conditions to obtain smaller fine particles. As a result, we found that theory of function-building fine particle preparation could be applied to synthesize nano-atomized fine particles of TiB2. The temperature of MTR process also decreased with reducing particle size of TiO2. When TiO 2 of ST-01, of which particle size is the smallest in our study, was used as a source of titanium and treated at 550°C, the smallest particles of TiB2 were obtained.
