Nano-atomization of Titanium Diboride Using Function-Building Fine Particle Preparation Method

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 fi...

Zusammenfassung: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 TiO2 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.
