Abstract

The production of titanium carbide (TiC) powders from ilmenite ore (FeTiO₃) powder by means of carbothermal reduction synthesis coupled with hydrochloric acid (HCl) leaching process was investigated. A mixture of FeTiO₃  and carbon powders was reacted at 1500°C for 1 hr under flowing argon gas. Subsequently, synthesized product of Fe-TiC powders
were leached by 10% HCl solutions for 24 hrs to get final product of TiC powders. The powders were characterized using X-ray diffraction, scanning electron and transmission electron microscopy. The product particles were agglomerated in the stage after the leaching process, and the size of this agglomerate was 12.8 µm with a crystallite size of 28.8 nm..
