:Irídio
Descrição:
Irídio é um metal de transição denso e branco prateado que pertence ao grupo dos elementos do platino, conhecido por sua notável resistência à corrosão e oxidação. Possui um alto ponto de fusão e é um dos metais mais resistentes à corrosão, tornando-o valioso em várias aplicações industriais. Irídio é tipicamente encontrado na natureza como uma liga com outros metais do grupo do platino e frequentemente é extraído de minérios de níquel e cobre. Seu número atômico é 77 e exibe uma variedade de estados de oxidação, sendo +3 e +4 os mais comuns em compostos. Irídio é utilizado em aplicações de alta temperatura, contatos elétricos e velas de ignição, bem como na produção de certos tipos de catalisadores. Além disso, devido à sua raridade e propriedades únicas, Irídio também é utilizado em instrumentos científicos especializados e no campo da joalheria. Sua alta densidade e dureza contribuem para sua durabilidade, enquanto sua inércia química o torna adequado para uso em ambientes hostis.

CAS:Produto Controlado<p>Iridium is a transition metal that belongs to the group of platinum-group metals. It has the ability to catalyze chemical reactions, especially in organic chemistry. Iridium can be used as a catalyst for the metathesis reaction, which involves the exchange of an organic group between two molecules. Iridium also has a redox potential that is higher than those of many other metals and this makes it useful for reducing other metals from their salts. The ligands are often coordinated to iridium through dative bonds with four ligands, forming a square planar geometry. This coordination geometry is not found in most organometallic complexes, which usually have octahedral or tetrahedral geometries. The complex is obtained by reacting iridium with picolinic acid and the reaction solution is then analyzed using X-ray diffraction to determine its structure.</p>Fórmula:IrPureza:Min. 95%Peso molecular:192.22 g/mol
