:Zirconium
Description :
Zirconium est un métal de transition avec le symbole Zr et le numéro atomique 40. Il se caractérise par son point de fusion élevé, son excellente résistance à la corrosion et sa forte affinité pour l'oxygène, ce qui conduit à la formation d'une couche d'oxyde protectrice. Zirconium est un métal gris argenté qui est relativement ductile et peut être facilement fabriqué sous diverses formes. Il se trouve principalement dans la nature sous forme de silicate de Zirconium et est souvent extrait par réduction du chlorure de Zirconium. Cet élément est remarquable pour sa faible section efficace de capture des neutrons thermiques, ce qui le rend précieux dans les applications nucléaires, en particulier dans les composants de réacteurs et le revêtement de combustible. De plus, Zirconium est utilisé dans la production de céramiques, de matériaux dentaires et de divers alliages en raison de sa résistance et de sa résistance à la chaleur et à la corrosion. Ses composés, tels que le dioxyde de Zirconium, sont utilisés dans une gamme d'applications, y compris les matériaux réfractaires et comme opacifiants dans les céramiques. Dans l'ensemble, les propriétés uniques de Zirconium en font un matériau important dans divers domaines industriels et technologiques.

CAS :Produit contrôlé<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>Formule :ZrDegré de pureté :Min. 95%Masse moléculaire :91.22 g/mol
