1, Titanium Introduction Basic Definition
Titanium (symbol Ti) is a chemical element with atomic number 22, located in period 4 and group IVB of the
periodic table. It is a transition metal. The name “titanium” is derived from the Titans of Greek mythology,
symbolizing its strength and lightness.
2, Titanium Discovery and Occurrence
Discovery: Titanium was first discovered in 1791 by British chemist William Gregor in minerals, and it was
formally named in 1795 by German scientist Martin Klaproth.
Occurrence: Titanium is abundant in the Earth’s crust (about 0.6%), ranking 9th in abundance. It primarily
exists in oxide forms in minerals such as ilmenite (FeTiO₃) and rutile (TiO₂).
3, Physical and Chemical Properties
Light and Strong: Titanium has a density of 4.5 g/cm³ (only 60% that of steel) but exhibits strength
comparable to steel, along with excellent fatigue resistance.
Corrosion Resistance: It forms a dense oxide layer (TiO₂) on its surface, making it resistant to corrosion from
seawater, chlorine, and other harsh environments.
High Melting Point: Approximately 1668°C, suitable for high-temperature applications.
Biocompatibility: Non-toxic and compatible with human tissues, making it ideal for medical implants.
4, Major Applications
Aerospace: Used in aircraft engines, spacecraft components (e.g., Boeing 787 fuselage), earning it the
nickname “space metal.”
Medical Field: Used in artificial joints, bone screws, dental implants, and more.
Chemical and Marine Industries: Corrosion-resistant pipes, desalination equipment.
Daily Life: High-end eyewear frames, sports equipment (golf clubs, bicycle frames), and electronic
device casings.
Emerging Technologies: Titanium alloys are used in 3D printing and lightweight components for new
energy vehicles.
5, Importance of Titanium Alloys
Pure titanium has limited strength, so it is often alloyed with elements like aluminum and vanadium to form
titanium alloys (e.g., Ti-6Al-4V). These alloys combine high strength, heat resistance, and corrosion resistance,
making them critical materials in advanced industries.
6, Production Challenges
Titanium extraction is complex (e.g., the Kroll process) and costly due to high-temperature reduction and
stringent anti-oxidation requirements, resulting in higher prices compared to common metals.

Conclusion
Titanium, known for its “lightweight, strong, and corrosion-resistant” properties, is a versatile metal in
modern industry. It plays a vital role in high-end technology and sustainable development, with the
potential to further revolutionize materials science in the future.
