· The historic difficulty in processing titanium resources from the OUI resulted from impurities, such as magnesium oxide, in the crude ore and concentrate products. Previous research found that a large portion of the magnesium is associated with the chemical composition of the ilmenite and cannot be removed using conventional processing techniques.

· The workhorse superplastic titanium alloy is Ti-6Al-4V, and the state-of-the-art in titanium superplastic forming is largely based on this alloy. However, a number of titanium alloys, especially the a-b alloys, exhibit superplastic behavior. Many of these materials, such as Ti-6Al-4V, are superplastic without special processing.

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.

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 ...
