The History and Industrial Development of Titanium
TLDR Titanium, a metal with attractive properties, remained hidden throughout most of human history due to its chemical proclivity to bond with other elements. Its practical use began in the 1960s with the development of the Kroll process, leading to its application in industries such as aerospace and medicine.
Timestamped Summary
00:00
Titanium, the ninth most abundant element in the Earth's crust, is a remarkable yet difficult metal to use that wasn't discovered until the late 18th century and wasn't practically used until the 1960s.
02:20
Titanium is a metal with attractive properties and is abundant, but it remained hidden throughout most of human history due to its chemical proclivity to bond with other elements.
04:08
Martin Heinrich Klapproth discovered the same oxide as Gregor and named it Titanium, but neither of them were able to isolate the element until Matthew Hunter developed a process in 1910 to produce metallic titanium.
05:59
The breakthrough in creating titanium for industrial use occurred in 1930 with the development of the Kroll process, which created a titanium sponge that could be further refined into pure titanium metal.
07:50
Titanium production in the early 1950s fell far short of expectations due to difficulties in working with the metal, leading to the discovery of titanium alloys that were easier to work with and the eventual development of the Lockheed A12 spy plane.
09:44
The construction of the A12 spy plane led to the development of new techniques for working with titanium and the discovery of its compatibility with bone, leading to its use in medical applications such as screws, plates, and dental implants.
11:38
Titanium, once reclassified after the Cold War, became more widely available for use in various industries, with the majority of it being used for titanium dioxide, a white pigment used in paints, plastics, paper, cosmetics, and toothpaste.
