:Ródio
Descrição:
Ródio é um metal de transição raro, de cor branco prateado, pertencente ao grupo dos metais do platino, conhecido por sua alta refletividade e resistência à corrosão e oxidação. Tem o número atômico 45 e é denotado pelo símbolo Rh. Ródio é utilizado principalmente em conversores catalíticos para automóveis, onde ajuda a converter gases nocivos em emissões menos tóxicas. Suas excelentes propriedades catalíticas também o tornam valioso em várias reações químicas, incluindo processos de hidrogenação e oxidação. Ródio é caracterizado por um alto ponto de fusão e densidade, contribuindo para sua durabilidade e eficácia em aplicações de alta temperatura. Além disso, é frequentemente utilizado em joias e como material de revestimento devido ao seu acabamento lustroso e à sua capacidade de realçar a aparência de outros metais. Apesar de suas propriedades benéficas, Ródio é considerado um dos metais preciosos mais caros, com seu preço influenciado pela dinâmica de oferta e demanda nos setores automotivo e industrial. Sua escassez e características únicas o tornam um elemento significativo tanto em aplicações industriais quanto em mercados de investimento.

CAS:Rhodium 5% on alumina is a chemical catalyst that is used in the oxidation of hydrocarbons and the reduction of nitro compounds. It is used in the process of catalytic conversion of hydrocarbons to produce gasoline, diesel fuel, and other fuels. Rhodium 5% on alumina has high resistance to hydrochloric acid, water vapor, and acid complex. This catalyst has been shown to be an effective catalyst for hydrogenation reactions with boron nitride as a support material. Rhodium 5% on alumina also has analytical chemistry applications due to its ability to bind up blood group antigens from animal sources or human blood samples.Pureza:Min. 95%Rhodium/tetra-n-octylammonium chloride colloid, purified (70-75% Rh)
