CAS 7440-54-2
:Gadolinium
Description :
Gadolinium est un métal rare de couleur argentée, malléable et ductile, classé sous la série des lanthanides dans le tableau périodique. Il a le numéro atomique 64 et est connu pour ses propriétés magnétiques uniques, en particulier sa capacité à devenir ferromagnétique à température ambiante, ce qui est relativement rare parmi les lanthanides. Gadolinium est hautement réactif, surtout sous forme de poudre, et peut s'oxyder rapidement lorsqu'il est exposé à l'air, formant une couche d'oxyde protectrice. Il a un point de fusion élevé et est souvent utilisé dans diverses applications, y compris en imagerie par résonance magnétique (IRM) comme agent de contraste en raison de ses propriétés paramagnétiques. De plus, les composés de Gadolinium sont utilisés dans des applications de capture de neutrons et comme phosphores dans certains types d'écrans. Le métal est généralement obtenu à partir de minéraux tels que la bastnäsite et la monazite et est souvent traité par des méthodes d'extraction complexes. Des précautions de sécurité sont nécessaires lors de la manipulation de Gadolinium et de ses composés, car ils peuvent être toxiques sous certaines formes et concentrations.

CAS :Produit contrôléGadolinium is a chemical element with symbol Gd and atomic number 64. Gadolinium is a silvery-white, malleable, ductile metal that resembles iron in its physical properties and reactivity. It is found in the Earth's crust only in trace amounts. Gadolinium is used as a component of alloys such as high-strength magnets and X-ray shielding, or to produce gadolinium ions for use in magnetic resonance imaging (MRI). Gadolinium can be toxic to humans if it enters the bloodstream and causes damage to the liver, bones, nervous system, heart, or other organs. In some cases, these adverse effects may be delayed up to 20 years after exposure.Formule :GdDegré de pureté :Min. 95%Masse moléculaire :157.25 g/molGadolinium powder, -200 mesh, 99.9% (REO)
