:Yttrium
Description :
Yttrium est un élément métallique argenté avec le numéro atomique 39 et est classé comme un métal de transition dans le tableau périodique. Il fait partie du groupe des éléments des terres rares et est connu pour son point de fusion élevé et sa stabilité thermique exceptionnelle. Yttrium est relativement stable dans l'air, formant une couche d'oxyde protectrice qui empêche une oxydation supplémentaire. On le trouve généralement dans des minéraux tels que le xénotime et la monazite et il est principalement extrait par divers procédés chimiques. Yttrium présente une variété d'états d'oxydation, le +3 étant le plus courant dans les composés. Il est utilisé dans diverses applications, y compris les phosphores pour les tubes de télévision couleur et les lumières LED, les supraconducteurs et comme agent d'alliage dans les métaux pour améliorer la résistance et la résistance à la corrosion. De plus, les composés de Yttrium sont utilisés dans des applications médicales, en particulier dans le traitement du cancer par le biais de radio-isotopes. Ses propriétés uniques font de Yttrium un matériau précieux dans les domaines industriel et technologique.

CAS :Produit contrôlé<p>Yttrium is a silvery-white, hard metal that is used primarily in alloys. Yttrium has an oxidation number of 3+, and it reacts with water vapor to form hydroxides. Yttrium can be found in wastewater treatment plants because it is resistant to corrosion by chlorine. It also binds to the monoclonal antibody and causes light emission, which can be observed using electrochemical impedance spectroscopy (EIS). The redox potential of yttrium is high, which allows it to oxidize other metals at lower concentrations than other metals would need to oxidize yttrium. Yttrium also has a coordination geometry of group P2, which means that its electrons are located in the same plane as the nucleus and are not as easily dislodged.</p>Formule :YDegré de pureté :Min. 95%Masse moléculaire :88.91 g/mol
