:Ítrio
Descrição:
Ítrio é um elemento metálico prateado com o número atômico 39 e é classificado como um metal de transição na tabela periódica. Faz parte do grupo dos elementos terras raras e é conhecido por seu alto ponto de fusão e excelente estabilidade térmica. Ítrio é relativamente estável no ar, formando uma camada de óxido protetora que impede a oxidação adicional. É tipicamente encontrado em minerais como xenotime e monazite e é extraído principalmente através de vários processos químicos. Ítrio exibe uma variedade de estados de oxidação, sendo +3 o mais comum em compostos. É utilizado em várias aplicações, incluindo fósforos para tubos de televisão colorida e luzes LED, supercondutores e como agente de liga em metais para melhorar a resistência e a resistência à corrosão. Além disso, compostos de Ítrio são utilizados em aplicações médicas, particularmente no tratamento do câncer através de radioisótopos. Suas propriedades únicas fazem de Ítrio um material valioso nos campos industrial e tecnológico.

CAS:Produto Controlado<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>Fórmula:YPureza:Min. 95%Peso molecular:88.91 g/mol
