250,000 tons of Titanium are produced every single year across the world and it is used in a wide range of industries from aerospace engineering to medical prosthetics. Almost all pure titanium used in industry is recovered from Titanium Chloride (TiCl4), a substance produced by a Schlenk line process. The chemical reaction of this formation is shown here:
2FeTiO3 + 7Cl2 + 6C → 2TiCl4 + 2FeCl3 + 6CO
The source of titanium used in this reaction is an Iron/Titanium ore known as ilmenite. The titanium in this reaction is highly reactive with oxygen and water (more so than the chlorine) and therefore they must be expelled from any reaction vessel. Carrying out this reaction under vacuum inert conditions allows the production of pure and unadulterated TiCl4, and without this technology it would be impossible to produce.
