CAS 7440-15-5
:Rênio
Descrição:
Rênio é um metal de transição com o símbolo Re e número atômico 75. É caracterizado por seu alto ponto de fusão, que é um dos mais altos entre todos os elementos, e sua aparência densa e prateada. Rênio é notável por sua excelente resistência à corrosão e oxidação, tornando-o adequado para aplicações em altas temperaturas. Apresenta uma variedade de estados de oxidação, sendo +7 o mais alto, e pode formar uma gama de compostos, incluindo óxidos de Rênio e sulfetos de Rênio. Rênio é utilizado principalmente em superligas para motores a jato e em catalisadores para processos de refino de petróleo. Seus isótopos, particularmente Rênio-186 e Rênio-188, têm aplicações em medicina nuclear. Além disso, Rênio é relativamente raro na crosta terrestre, frequentemente encontrado em minérios de molibdenita, e é tipicamente extraído através de processos metalúrgicos complexos. No geral, as propriedades únicas de Rênio o tornam um material valioso em várias aplicações industriais e tecnológicas.
