O QUE SIGNIFICA ZIRCONIUM EM INGLÊS
Zircônio
Zircônio é um elemento químico com o símbolo Zr, número atômico 40 e massa atômica de 91.224. O nome do zircônio é retirado do zircão mineral, a fonte mais importante de zircônio, e da palavra persa "zargun - زرگون", que significa "dourado". É um metal de transição brilhante, cinza-branco e forte que se assemelha ao hafnium e, em menor medida, ao titânio. O zircónio é usado principalmente como refratário e opacificante, embora seja usado em pequenas quantidades como um agente de liga por sua forte resistência à corrosão. O zircónio forma uma variedade de compostos inorgânicos e organometálicos, tais como dióxido de zircónio e dicloreto de zirconoceno, respectivamente. Cinco isótopos ocorrem naturalmente, três dos quais são estáveis. Os compostos de zircônio não possuem papel biológico conhecido.
definição de zirconium no dicionário inglês
A definição de zircónio no dicionário é um elemento metálico branco-acinzentado, que ocorre principalmente em zircão, que é excepcionalmente resistente à corrosão e possui baixa absorção de neutrões. É usado como revestimento em plantas nucleares e químicas, como um desoxidante em aço e ligado com nióbio em ímãs supercondutores. Símbolo: Zr; No. atômico: 40; peso atômico: 91.224; valência: 2, 3 ou 4; densidade relativa: 6.506; ponto de fusão: 1855 ± 2 ° C; Pb em ebulição: 4409 ° C.
