Titanium: Properties, History, and Industrial Uses
This paper provides a comprehensive overview of titanium (Ti), the 22nd element on the Periodic Table. It traces the metal's discovery by William Gregor in 1791 and its naming by Martin Klaproth in 1793, examines its key chemical and physical properties, and explains the Kroll process used for commercial extraction. The paper also surveys titanium's historical military applications during the Cold War, its current uses across aerospace, medicine, consumer products, and manufacturing industries, and analyzes market pricing trends from 2003 to the present. The discussion concludes with an outlook on titanium's future demand given its abundance, versatility, and ongoing military and industrial relevance.
- Discovery and Naming of Titanium: Gregor and Klaproth independently discover and name titanium

What makes this paper effective
- Balances historical narrative with technical detail, making scientific content accessible to a general audience without sacrificing accuracy.
- Uses specific data points—pricing figures, production volumes, and consumption statistics from the USGS—to ground economic claims in authoritative sources.
- Moves logically from discovery and chemistry through to extraction, applications, and market analysis, giving the paper a clear expository arc.
Key academic technique demonstrated
The paper demonstrates effective integration of multiple source types: a chemistry reference (Emsley), a history of elements text (Krebs), and a government statistical database (USGS). Each source is deployed at the appropriate point in the argument—Krebs for historical context, Emsley for technical chemistry, and USGS for market data—showing how to triangulate evidence across disciplines within a short expository essay.
Structure breakdown
The paper opens with discovery and naming, then moves into physical and chemical properties, followed by extraction methods, Cold War and commercial applications, current U.S. market statistics and pricing history, and concludes with a forward-looking demand forecast. The six-section structure progresses from past to present to future, a classic chronological-analytical pattern well suited to a scientific overview essay.
Discovery and Naming of Titanium
The symbol for the metal titanium on the Periodic Table is Ti, a direct abbreviation of the metal's name. The metal was discovered in Great Britain—Cornwall, to be exact—by a clergyman and mineralogist named William Gregor in 1791. However, Gregor did not get to name the element, at least not as it is commonly recognized today. That honor went to Martin Klaproth, a German chemist who had already discovered uranium and zirconium two years prior and who would later discover cerium in 1803. Klaproth discovered titanium independently of Gregor in 1793 and, unaware that it was the same substance Gregor had identified, named it titanium after the Greek gods the Titans, because in his view it was "the incarnation of natural strength" ("History of Titanium"). Gregor had named his discovery "gregorite" two years earlier, but Klaproth's name is what endured.
Chemical Properties and Natural Occurrence
Titanium was not actually isolated until more than a century after its discovery—in 1910. The element occurs naturally as part of chemical combinations and is most often found in rutile and ilmenite. It is the ninth most common element in Earth's crust, where it makes up almost a quarter of the crust's composition. As the 22nd element on the Periodic Table, titanium has an atomic weight of 47.867 amu and a low density of 4,510 kg/m³, approximately 60% lower than the density of steel ("History of Titanium"). It is highly corrosion-resistant, with high passivity, and is also nontoxic—properties that make it well suited for use in medical implants in humans.
Klaproth discovered his titanium source in a sample of rutile obtained from Boinik, while Gregor's discovery came from a sample of manaccanite (Krebs). The difficulty of isolating titanium stems from the cost of the process required to do so.
Extraction and Isolation Methods
Titanium can be isolated by heating it with carbon, as is done in the smelting of iron, because the element then binds with carbon to create titanium carbide (Emsley). However, it was not until 1932 that William Kroll, the metallurgist famous for developing the Kroll process, demonstrated that titanium could be extracted from ore by reducing titanium tetrachloride with calcium—and later with magnesium and sodium. The Kroll process remains the method primarily used for the commercial isolation of titanium today (Krebs).
