Calciothermic reduction of titanium oxide is a new process to prepare titanium powder with short route and low cost.In this paper,effect of the amount of additive(CaCl2) and reduction time on reduced products is studied at 1000℃ in vacuum atmosphere.The results show all the titanium oxide is converted into Ti metal after reduction for 1.5 h when mass ratio of CaCl2 to TiO2 in raw materials is 1:4 and the reduction reaction can be promoted with the addition of CaCl2.After pickling,the obtained Ti powder was detected by X-ray diffractometer,scaning electron microscopy,and oxygen and nitrogen analyzer.It is found that there is no metallic impurity other than Ti in the titanium powder with oxygen content of 1 000×10-6,nitrogen content of 170×10-6.
