Seven Elements That Have Changed the World
“Strong, lightweight and corrosion resistant, titanium was presented as the wonder metal of the future.1 Titanium was discovered in 1791 by William Gregor, an English clergy-man, mineralogist and chemist, when he isolated some ‘black sand’ from a river in the Manaccan valley in Cornwall. We now know this as the mineral ilmenite, an iron-titanium oxide, from which he produced an impure oxide of a new element that he called manaccanite. Four years later, Martin Klaproth, a German chemist, isolated... titanium dioxide from titanium's other major ore, rutile. He called the new element titanium, after the gods of Greek mythology the Titans, who were imprisoned inside the Earth by their father, Uranus. Klaproth also discovered uranium; he chose abstract names for both elements as, at the time, their properties were not fully known.2 Yet, coincidentally, Klaproth’s name turned out to be apt: like the Titans, trapped inside the Earth, titanium is strongly bound in its ore and is very difficult to extract.MoreLess
