초록
The ultra-fine and less agglomerated titanium carbonitride particles were successfully synthesized by magnesiothermic reduction with low feeding rate of TiCl4+1/4C2Cl4 solution. The sub-stoichiometric titanium carbide (TiC0.5~0.6)particles were produced by reduction of chlorine component by liquid magnesium at 800oC of gaseous TiCl4+1/4C2Cl4and the heat treatments in vacuum were performed for 5 hours to remove the residual magnesium and magnesium chloride mixed with produced TiC~0.5. The final TiC~0.5N0~0.5 particle with near 100 nm in mean size and high specific surface area of 65 m2/g was obtained by nitrification under nitrogen gas at 1,150oC for 2 hrs.
