  • Kroll process metallurgy Britannica

    In titanium: Occurrence, properties, and uses. In the Kroll process, one of the ores, such as ilmenite (FeTiO 3) or rutile (TiO 2), is treated at red heat with carbon and chlorine to yield titanium tetrachloride, TiCl 4, which is fractionally distilled to eliminate impurities such as ferric chloride, FeCl 3.The TiCl 4 is then reduced with.

    Mar 15, 2005· Process. In the Kroll process, the TiCl 4 is reduced by liquid magnesium to give titanium metal: + + The reduction is conducted at 800–850 °C in a stainless steel retort. 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. The resulting porous metallic titanium sponge is purified by

  • Kroll Process an overview ScienceDirect Topics

    The Kroll process is a multi-step, energy-intensive technique to produce metallic titanium from the stable oxide ore. During all subsequent processes and regardless of whether a melt or powder is involved, avoidance of contamination by oxygen, carbon and nitrogen is essential. Titanium features high solubility for these elements connected with

    Jan 01, 2020· Fig. 17.1 shows a flowchart of the Kroll process. It can be divided into five major sub-processes, as follows,,,: (1) Chlorination and purification of titanium ore The raw materials are chlorinated and distillated to produce pure titanium tetrachloride (TiCl 4). (2) Reduction Pure titanium tetrachloride is reduced using molten magnesium to produce titanium sponge.

    Sep 28, 2017· The Kroll Process is named after William J. Kroll, who invented the process in 1940 to produce zirconium. The Kroll Process is comprised of 6 steps to produce the titanium we have come to use and benefit from: Step 1: The pure titanium ore is converted into a sponge through conducting an electrical charge through the ore. This is done in a

  • What Is the Kroll Process? (with picture)

    Nov 09, 2020· The Kroll process begins by passing chlorine gas through rutile in a chlorinator. During the first stage of the process, titanium tetrachloride and chlorides are produced from the ore. Oxygen is removed from the titanium tetracholdire through a distillation process, and this leaves the titanium tetrachloride in a liquid form.
