The William Gregor (1761 – 1817)
Titanium was first found in Cornish beach sands by Cornwall clergy with amateur mineralogist William Gregor in 1791.
Martin Heinrich Klaproth (1743 - 1817)
In 1795, German chemist Martin Heinrich Klaproth rediscovered this oxide when analyzing the red rutile produced in Hungary. He decided to name the new element “Titanium” originated from “Titanic” in Greek mythology.
Chemist IJ. Berzelius
It was not until in 1825 that chemist IJ. Berzelius found the method of reduceing potassium fluorotitanate (K2TiF6) by potassium metal. Although it means that people first got the real sense of titanium metal in the laboratory, it is poor purity, a small amount, and cannot be used for research.
Swedish scholar, Nilson & Petso
Swedish scholars Nilson and Petso in 1887 isolated the metallic titanium (TiCl4)with impurity content <5%. Their method of using sodium was later refined into the hunter process.
Anton Eduard van Arkel & Jan Hendrik de Boer
In 1925, Anton Eduard van Arkel and Jan Hendrik de Boer used the method of thermal decomposition of Til on hot tungsten wire to produce pure metallic titanium with excellent ductility no matter under the cold or hot state.
American chemist Matthew A. Hunter
In 1910, American chemist Matthew A. Hunter first reduced TiCI with sodium to produce metallic titanium with a purity of 99.9%.
Luxembourg scientist W.J. Kroll
In 1940, Luxembourg scientist W.J. Kroll used magnesium to reduce TiCl4 to produce pure titanium.
Since then, the magnesium reduction method (also known as the Kroll process) and the sodium reduction method (also known as the Hunter method) have become industrial methods for producing sponge titanium.
DuPont (In September 1948)
In September 1948, DuPont of the United States produced sponge titanium by the Kroll method and magnesium reduction TiC14 method, getting its titanium with purity above 99%. In that year, the United States produced a total of 3 tons of sponge titanium.
Japan Osaka Titanium Co., Ltd (in 1951)
Japan Osaka Titanium Co., Ltd. successfully produced 20 kg of sponge titanium in the laboratory in 1951.
UK (in 1994)
Due to the shortage of magnesium raw materials in the UK, the production of titanium sponge used to adopt sodium thermal reduction method, with the output of about 2500T /y. After the closure of the only titanium plant in 1994, the UK has withdrawn the world's titanium sponge producers.
Podorsk chemical plant (in June 1956)
In February 1954, the first batch of titanium was produced in Russia on an industrial scale by the magnesium thermal process at the Podorsk chemical plant. The first batch of sponge titanium was made in June 1956.
China (In 1958)
In 1958, China's first batch of titanium sponge was produced on a laboratory scale of 10 kg.
