Abstract

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.
