Production Rate of Titanium by Reduction of Titanium Tetrachloride with Magnesium

Abstract

The reaction rate of the reduction of TiCl₄ with Mg was studied by means of an impulse response method. In the case of gaseous TiCl₄ feed, the reaction rate was proportional to the concentration of TiCl₄ and the apparent activation energy was obtained as 59 kJ · mol^-1 In the case where liquid TiCl₄ was fed onto the molten Mg, TiCl₄ was vaporized and then reacted with Mg. The reaction was found to be controlled by the vaporization process of TiCl₄. Therefore, the production rate of Ti can be increased by improvement of the vaporization process.
