This is a timeline of titanium, attempting to describe important events related to the discovery, science and industrial development of the metal.

Big picture

Time period	Development summary
18th century	Titanium is discovered in the last decade of the century, withe reports of William Gregor and Martin Heinrich Klaproth.
19th century	Methods to obtain pure titanium start development in the century. However, industrial production is not yet achieved.
20th century	Titanium is first obtained as pure metal at the beginning of the century. The Hunter process becomes the first industrial process to produce pure ductile metallic titanium.
1930–1950	The only methods allowing the processing of titanium into useful shapes are the powder metallurgy techniques applied to fines of titanium sponge.^[1] The Kroll process, developed by William Justin Kroll, would allow for the commercial extraction of metallic titanium from ore.^[2]
1950s–1960s	Titanium has a relatively short production history. The first commercial quantities of titanium are produced at around 1950.^[3] In the early 1950s, a number of companies enter the business in the United States, with strong government support.^[3] In the 1950s and 1960s, the Soviet Union pioneers the use of titanium in military and submarine applications^[4] (Alfa class and Mike class)^[5] as part of programs related to the Cold War.^[6]
1980s	A rise in titanium shipments occur in the decade, largely in part due to the United States military buildup and the increase of aerospace and other nonmilitary uses.^[3]
1990s	Early in the decade, with the ending of the Cold War and the collapse of the Soviet Union, defense expenditures decline and the military demand for titanium decreases.^[3]^[7]
2000s<	China emerges as a global player in titanium sponge production.^[8]

Full timeline

Year	Event type	Details	Country/region
1790	Discovery	British Reverend William Gregor in England discovers the element titanium.^[3]^[9]^[10]^[11]	United Kingdom
1791	Scientific development	William Gregor presents a description and chemical composition of some black magnetic sands found on the southern Cornish coast. Gregor's analysis of the black sand correspond roughly to that of mineral ilmenite (FeTiO₃).^[3]	United Kingdom
1795	Scientific development	German chemist Martin Heinrich Klaproth identifies the oxide of an unknown element, the same as the one reported by Gregor. Klaproth names the element titanium after the Titans, the powerful sons of the earth in Greek mythology.^[12]^[13]^[14]^[15]	Germany
1887	Scientific development	L.F. Nilson and O. Peterson obtain a product of 97.4% purity by reducing titanium tetrachloride with sodium in an airtight steel cylinder.^[3]
1906	Scientific development	New Zelander metallurgist Matthew Hunter General Electric in the United States produces the first pure titanium metal.^[3]	United States
1910	Scientific development	Matthew Hunter achieves the production of pure metallic titanium (99.9%). The later called Hunter process is the first industrial process to produce pure ductile metallic titanium.^[16]^[8]
1925	Scientific development	Titanium of very high purity is made in small quantities when Dutch chemists Anton Eduard van Arkel and Jan Hendrik de Boer discover the iodide (or crystal bar) process, by reacting with iodine and decomposing the formed vapours over a hot filament to pure metal.^[17]^[3]^[8]	Netherlands
1932	Scientific development	Luxembourgish metallurgist William Justin Kroll proves that titanium can be produced by reducing titanium tetrachloride (TiCl₄) with calcium.^[1] The process, known today as Kroll process, would replace the Hunter process for almost all commercial production.^[18]
1937	Scientific development	William Justin Kroll invents the magnesium reduction process (reducing titanium tetrachloride with magnesium) by utilizing an inert argon atmosphere to protect the titanium metal from reoxidizing. Kroll is credited with developing the technology that would lead eventually to the large-scale commercialization of titanium metallurgy.^[16]^[8]
1938	Scientific development	William Justin Kroll, at the Bureau of Mines in Albany, Oregon, produces the first display of cold ductile titanium in the United States. The work of W.J. Kroll is considered the start of the present large-scale titanium industry.^[3]	United States

1951	Organization	The Mallory-Sharon Titanium Corporation is organized by P.R. Mallory Company and Sharon Steel Corporation.^[3]	United States
1951	Facility	The United States National Lead operates the Bureau of Mines titanium sponge plant, and at around the same time, constructs pilot plants for sponge.^[3]	United States
1951	Application	Clinical and laboratory experience demonstrates the suitability of titanium for implant use, specifically, because of its excellent strenght, corrosopm resistance, and biocompatibility.^[19]
1952	Scientific development	The United States Bureau of Mines reports the removal of magnesium and magnesium chloride from titanium sponge by vacuum distillation.^[3]	United States

2015	Production	India opens titanium sponge plant at Chavara in Kerala, and becomes the seventh country in the world producing titanium sponge commercially.^[26]	India
2017	Financial	The global titanium powder market is valued at US$3230 million in the year.^[27] Also, the global Titanium Aluminide Alloy market is valued at US$ 140 million.^[28]
