titanium
Definition
Titanium is a chemical element with the symbol Ti and atomic number 22. It is a transition metal that is strong, lightweight, and corrosion-resistant.
Titanium is the ninth most abundant element in the Earth's crust, but it is not found in its pure form. It is found in combination with other elements, such as iron and oxygen.
Titanium is extracted from its ores by a process called smelting. The smelting process involves heating the ore to a high temperature and then adding a reducing agent, such as carbon.
Titanium has a number of properties that make it useful in a variety of applications. It is strong, lightweight, corrosion-resistant, and biocompatible.
Titanium is used in a wide variety of applications, including:
- Aircraft and spacecraft
- Medical implants
- Jewellery
- Sports equipment
- Marine applications
- Chemical processing
