Gadolínio

Descrição:

Gadolínio é um metal raro de cor prateada, maleável e dúctil, classificado sob a série dos lantânidos na tabela periódica. Possui o número atômico 64 e é conhecido por suas propriedades magnéticas únicas, particularmente sua capacidade de se tornar ferromagnético à temperatura ambiente, o que é relativamente raro entre os lantânidos. Gadolínio é altamente reativo, especialmente em forma de pó, e pode oxidar rapidamente quando exposto ao ar, formando uma camada de óxido protetora. Tem um alto ponto de fusão e é frequentemente utilizado em várias aplicações, incluindo em ressonância magnética (RM) como agente de contraste devido às suas propriedades paramagnéticas. Além disso, compostos de Gadolínio são utilizados em aplicações de captura de nêutrons e como fósforos em certos tipos de telas. O metal é tipicamente obtido de minerais como bastnasita e monazita e frequentemente processado através de métodos de extração complexos. Precauções de segurança são necessárias ao manusear Gadolínio e seus compostos, pois podem ser tóxicos em certas formas e concentrações.

Gadolinium 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.
