The main study focused on getting titanium by electrolysis reduction of TiO2in salt, namely, rearches about experiment conditiones and processing parameters of FFC process, were sutdied. Preparation of the cathode, choice and pretreatment of the salt, improvement of the electrolysis equipment and control of the parameters during electrolysis were carefully investigated in home-made equipment. Preparation of the cathode includesshaping under the press of 40Mpa, sintering at 550 for 1 hour and at 900 for 8 hours and threading with molybdenum bar; Considering the literatures we choose CaCl2 as salt for preparation titanium. Pretreatment of salt is for 1 hour at 100 and for 2 hours at 300. Partial pressure of oxygen which need lower than -7Pa to reduct titanium oxides and hygroscopic property of salt need a sealed equipment to electrolyse. And finally essfully designed a satisfied one
