:Circonio
Descripción:
Circonio es un metal de transición con el símbolo Zr y el número atómico 40. Se caracteriza por su alto punto de fusión, excelente resistencia a la corrosión y fuerte afinidad por el oxígeno, lo que conduce a la formación de una capa de óxido protectora. Circonio es un metal de color gris plateado que es relativamente dúctil y se puede fabricar fácilmente en varias formas. Se encuentra principalmente en la naturaleza en forma de silicato de Circonio y a menudo se extrae mediante la reducción de cloruro de Circonio. Este elemento es notable por su baja sección transversal de captura de neutrones térmicos, lo que lo hace valioso en aplicaciones nucleares, particularmente en componentes de reactores y revestimientos de combustible. Además, Circonio se utiliza en la producción de cerámicas, materiales dentales y diversas aleaciones debido a su resistencia y resistencia al calor y la corrosión. Sus compuestos, como el dióxido de Circonio, se utilizan en una variedad de aplicaciones, incluidos materiales refractarios y como opacificantes en cerámicas. En general, las propiedades únicas de Circonio lo convierten en un material importante en varios campos industriales y tecnológicos.

CAS:Producto controlado<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>Fórmula:ZrPureza:Min. 95%Peso molecular:91.22 g/mol
