:Zircônio
Descrição:
Zircônio é um metal de transição com o símbolo Zr e número atômico 40. É caracterizado por seu alto ponto de fusão, excelente resistência à corrosão e forte afinidade pelo oxigênio, o que leva à formação de uma camada de óxido protetora. Zircônio é um metal cinza-prateado que é relativamente dúctil e pode ser facilmente fabricado em várias formas. É encontrado principalmente na natureza na forma de silicato de Zircônio e muitas vezes é extraído através da redução do cloreto de Zircônio. Este elemento é notável por sua baixa seção de captura de nêutrons térmicos, tornando-o valioso em aplicações nucleares, particularmente em componentes de reatores e revestimentos de combustível. Além disso, Zircônio é utilizado na produção de cerâmicas, materiais dentários e várias ligas devido à sua resistência e resistência ao calor e à corrosão. Seus compostos, como o dióxido de Zircônio, são utilizados em uma variedade de aplicações, incluindo materiais refratários e como opacificantes em cerâmicas. No geral, as propriedades únicas de Zircônio fazem dele um material importante em vários campos industriais e tecnológicos.

CAS:Produto 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
