Abstract

"Pó DE NIóBIO, CORPO SINTERIZADO DO MESMO, PRODUTO QUIMICAMENTE MODIFICADO DO MESMO E CAPACITOR UTILIZANDO OS MESMOS". A invenção refere-se a um pó de nióbio capaz de providenciar um capacitor com pequenas quantidades de corrente de vazamento, em que a concentração média de nitrogênio na camada de 50 a 200 nm desde a superfície é 0,29 a 4% em peso e preferivelmente controlar a da profundidade em 50 nm desde a superfície em 0,19 a 1% em peso, o corpo sinterizado, o corpo formado e o capacitor que os utiliza.
