High-Purity Titanium Metal Produced for the First Time

The titanium that Gregor and Klaprot discovered at the time was powdered titanium dioxide instead of titanium. Since titanium oxide is extremely stable, and titanium metal can be directly and intensely combined with oxygen, nitrogen, hydrogen, carbon, etc., elemental titanium is difficult to prepare. It was not until 1910 that the American chemist Hunter first used titanium to reduce TiCI to produce metal titanium with a purity of 99.9%.
