:Iridio
Descrizione:
Iridio è un metallo di transizione denso e bianco argenteo che appartiene al gruppo dei metalli del platino, noto per la sua notevole resistenza alla corrosione e all'ossidazione. Ha un alto punto di fusione ed è uno dei metalli più resistenti alla corrosione, rendendolo prezioso in varie applicazioni industriali. Iridio si trova tipicamente in natura come un legame con altri metalli del gruppo del platino ed è spesso estratto da minerali di nichel e rame. Il suo numero atomico è 77 e presenta una varietà di stati di ossidazione, con +3 e +4 che sono i più comuni nei composti. Iridio è utilizzato in applicazioni ad alta temperatura, contatti elettrici e candele di accensione, così come nella produzione di alcuni tipi di catalizzatori. Inoltre, a causa della sua rarità e delle sue proprietà uniche, Iridio è utilizzato anche in strumenti scientifici specializzati e nel campo della gioielleria. La sua alta densità e durezza contribuiscono alla sua durata, mentre la sua inerzia chimica lo rende adatto per l'uso in ambienti difficili.

CAS:Prodotto controllato<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>Formula:IrPurezza:Min. 95%Peso molecolare:192.22 g/molRef: 3D-FI54944
