Titanium
Titanium
Titanium (pronounced /taɪˈteɪniəm/) is a chemical element with the symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density, and high strength.
Etymology
The name Titanium was derived from the Titans of Greek mythology. It was discovered in 1791 by the clergyman and amateur geologist, William Gregor. He named the element menachanite, after his home county of Cornwall, England. However, it was later renamed by Martin Heinrich Klaproth, a German chemist, who discovered the same element independently. He named it Titanium after the Titans, the first sons of the earth in Greek Mythology.
Properties
Titanium is known for its high strength-to-weight ratio. It is a strong metal with low density that is quite ductile (especially in an oxygen-free environment), lustrous, and metallic-white in color. The relatively high melting point (more than 1,650 °C or 3,000 °F) makes it useful as a refractory metal.
Uses
In the medical field, Titanium is used for its non-toxic and biocompatible properties. It is used in a variety of applications such as surgical implements and implants, such as hip balls and sockets (joint replacement) that can stay in place for up to 20 years. Titanium is also used in dental implants and orthodontic braces.
