Titanium is a non-magnetic silvery metal with the chemical symbol Ti. It is resistant to corrosion and has a very high strength-to-weight ratio. Titanium is predominantly associated with the minerals rutile and ilmenite (Table 1). Titanium is used mainly as titanium dioxide for white pigments. Mineral Name.

The further processing of titanium alloys is very similar to that of nickel-based superalloys. Billet converting, thermomechanical processing and machining are typically used to produce final components and have to be controlled tightly to guarantee good mechanical properties (Fig. 12.7).Although investment casting is possible for titanium alloys, the high …

Purified TiO 2 can also be used as the feedstock for chlorination, although that would not have any advantages over using the concentrated ore. Two typical processes exist for production of pure TiO 2 separating titanium oxide: one is the sulfate process and the other is the chloride process. The embodied energy of pure TiO 2 is reported to be …

The Kroll Process. Regardless of the final usage titanium must first be removed from its ore and turned into pure titanium. This is done by processing titanium oxide manufactured from either ilmenite or rutile though the Kroll process. The output is a titanium sponge which is purified, melted and alloyed with other metals.
