Abstract

"COMPOSIçõES DE METAL PARA VáLVULA E MéTODO". Artigos de metal de válvula tais como fio, folha ou pó tendo um segundo metal, preferivelmente em uma margem periférica, preparados revestindo-se o metal da válvula com uma solução de sal do aditivo metálico e tratando-se termicamente na presença de um absorvedor de oxigênio para remover o oxigênio do metal da válvula e o ânion do sal metálico do aditivo metálico. Para o fio de tântalo um preferido segundo metal é o níquel. Um absorvedor de oxigênio preferido é o magnésio. Fio de tântalo contendo níquel é útil para ligação melhorada a granulados de pó de tântalo prensado sinterizados na produção de capacitores eletrolíticos.
