Process. In the Kroll process, titanium tetrachloride is reduced by liquid magnesium to give titanium metal: The reduction is conducted at 800–850 °C in a stainless steel retort. [2] [3] Complications result from partial reduction of the TiCl 4, giving to the lower chlorides TiCl 2 and TiCl 3. The MgCl 2 can be further refined back to magnesium.
