The experimental results indicate that the reduction reaction occurs very rapidly when the mass ratio of CaCl2 to TiO2 is 1:2 from 0min to 30min, and the titanium suboxides were further reduced from 30min to 480min at 1000°C. The content of CaCl2 influences the reduction products and the reduction rate obviously, and the suitable mass ratio of CaCl2 to TiO2 is 1:2 under these experimental conditions. Ti powders with oxygen content of 1000ppm, nitrogen content of 120ppm, and chlorine content of 80ppm were obtained at 1000°C for 360min.
