Zirconium

Description:

Zirconium is a transition metal with the symbol Zr and atomic number 40. It is characterized by its high melting point, excellent corrosion resistance, and strong affinity for oxygen, which leads to the formation of a protective oxide layer. Zirconium is a silvery-gray metal that is relatively ductile and can be easily fabricated into various shapes. It is primarily found in nature in the form of zirconium silicate and is often extracted through the reduction of zirconium chloride. This element is notable for its low thermal neutron capture cross-section, making it valuable in nuclear applications, particularly in reactor components and fuel cladding. Additionally, zirconium is used in the production of ceramics, dental materials, and various alloys due to its strength and resistance to heat and corrosion. Its compounds, such as zirconium dioxide, are utilized in a range of applications, including refractory materials and as opacifiers in ceramics. Overall, zirconium's unique properties make it an important material in various industrial and technological fields.
