Història
William Gregor found the oxide of titanium in ilmenite in 1791.
Martin Heinrich Klaproth independently discovered the element in rutile in 1795 and named it.
The pure metallic form was only obtained in 1910 by Matthew A. Hunter.
In 1936, the Kroll Process made the commercial production of titanium possible.
