英文摘要	TiCl2 is a promising precursor for producing metallic titanium alloys and titanium-based ceramics. However, the effective synthesis of high-quality TiCl2 powder remains challenging. Herein, a fluidized bed reactor (FBR) providing a high gas-solid contact area was employed to synthesize TiCl2 powder using are liable TiCl4-Ti reaction system. Optimal reaction conditions (600 degrees C and 120 min) were determined for the proposed Ti-TiCl4 system by kinetic investigation. A dense Ti layer was regenerated upon the original surface of the Ti powder as a result of TiCl2 disproportionation at high temperature (above 700 degrees C), which impeded infiltration by gaseous TiCl4. The particle size of the Ti reducing agent played a vital role in the production of TiCl2 powder. A mean particle size of 24.5 mu m was confirmed to be the most feasible option based on the optimal chlorinated depth (17 mu m).
