CAS 7440-19-9: Samário
Descrição:
Samário é um elemento metálico de cor prateada classificado como um lantânio na tabela periódica, com o número atômico 62. É relativamente estável no ar e não mancha facilmente, embora possa reagir com água e ácidos para formar hidróxido de Samário e sais de Samário. Samário exibe um alto ponto de fusão e é conhecido por suas propriedades magnéticas, tornando-o útil na produção de ímãs permanentes, particularmente ímãs de Samário-cobalto, que são conhecidos por sua alta resistência à desmagnetização. Além disso, Samário é utilizado em várias aplicações, incluindo reatores nucleares, onde atua como um absorvedor de nêutrons, e na fabricação de fósforos para tubos de televisão coloridos e luzes LED. O elemento é tipicamente obtido de minerais como monazita e bastnasita, e muitas vezes é utilizado na forma de ligas ou compostos. Os isótopos de Samário têm aplicações na medicina, particularmente no tratamento do câncer, devido às suas propriedades radioativas. No geral, Samário é um elemento versátil com uma importância industrial e tecnológica significativa.
