: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.

CAS:Controlled Product<p>Zirconium is a metal that has been shown to be highly resistant to corrosion in vivo and in humans. Zirconium oxide, also known as zirconia, is a ceramic material with a high melting point and thermal expansion coefficient. It can be used in the production of dental restorations, such as crowns and bridges, because it is not attacked by hydrochloric acid in the mouth. Zirconium can be combined with other metals to produce alloys with desired properties. The biological properties of zirconium are related to its chemical stability and resistance to oxidation. The reaction mechanism for zirconium compounds is based on the formation of metal carbonyls. This metal has been shown to have human serum levels that are low enough so that it does not interfere with blood coagulation or platelet aggregation reactions. Zirconium has been studied extensively using x-ray diffraction data collected from crystals grown from human serum.</p>Formula:ZrPurity:Min. 95%Molecular weight:91.22 g/mol
