process for economic production of titanium sponge on industrial scale and currently over 97% of the world capacity is exclusively by this route. The Kroll sponge production technology involves the following process steps: (i) preparation of TiCI 4

Kroll process | metallurgy | Britannica

The process of reduction of titanium tetrachloride uses magnesium (Kroll process), the Hunter process using sodium as a reductant is also practices. This chapter discussed the production of titanium sponge from titanium tetrachloride, with a brief description of the processes used to generate and purify titanium tetrachloride.

How Is Titanium Made? » Science ABC

… reduction of hafnium tetrachloride ( Kroll process, which is also used for titanium) and by the thermal decomposition of tetraiodide (de Boer–van Arkel process). titanium production process. 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 ...

Titanium - Wikipedia

Via the Kroll process, TiCl 4 is produced in the conversion of titanium ores to titanium dioxide, e.g., for use in white paint. It is widely used in organic chemistry as a Lewis acid, for example in the Mukaiyama aldol condensation. In the van Arkel process, titanium tetraiodide (TiI 4) is generated in the production of high purity titanium metal.
