William Gregor
Titanium was first identified by William Gregor in 1791 and later named by Martin Heinrich Klaproth after the Titans of Greek mythology. Industrial titanium production became practical after the Kroll process was developed in the 20th century.

- Medical and dental implants because titanium is strong and biocompatible
- Titanium dioxide as a white pigment in paints, plastics, paper and sunscreens
- Marine and chemical equipment where corrosion resistance is important
- Titanium nitride and titanium carbide hard coatings for cutting tools
Titanium has no known essential biological role, but it is highly biocompatible. Its stable oxide surface helps titanium implants integrate well with bone and tissue.
- Titanium has one of the best strength-to-weight ratios among structural metals.
- Titanium resists seawater corrosion because a protective TiO₂ film forms on its surface.
- TiO₂ is one of the most important white pigments in the world.
- Ti-6Al-4V is the best-known titanium alloy and is widely used in aerospace and medical applications.
- The Kroll process reduces TiCl₄ with magnesium under controlled conditions to make titanium metal.
- Titanium has atomic number 22 and belongs to group 4.
- Its electron configuration is [Ar] 3d² 4s².
- The most common oxidation state is +4, as in TiO₂ and TiCl₄.
- Titanium’s biocompatibility is linked to the stable oxide film on its surface.

What is titanium used for?
Titanium is used in aerospace alloys, medical implants, marine equipment, sports equipment, pigments and hard coatings.
Why is titanium used in implants?
Titanium is strong, lightweight, corrosion-resistant and biocompatible, so bone and tissue generally tolerate it well.
What is titanium dioxide used for?
Titanium dioxide is used as a white pigment in paints, plastics and paper, and as a UV-filtering material in sunscreens.
What is Ti-6Al-4V?
Ti-6Al-4V is a widely used titanium alloy containing aluminum and vanadium, valued for aerospace parts and medical implants.
What is the Kroll process?
The Kroll process produces titanium metal by reducing titanium tetrachloride with magnesium in an inert atmosphere.
