Abstract

"MéTODOS PARA REDUZIR PARCIALMENTE UM óXIDO DEMETAL DE NIóBIO E óXIDOS DE NIóBIO REDUZIDOS POROXIGêNIO". São descritos métodos para reduzir, pelo menosparcialmente, um óxido de nióbio onde o método inclui tratamentotérmico do óxido de nióbio em presença de um material absorventemetálico e em atmosfera que permita a transferência dos átomos deoxigênio do óxido de nióbio para o material absorvente metálico, epor um tempo suficiente e em uma temperatura suficiente paraformar um óxido de nióbio reduzido por oxigênio. óxidos de nióbioe/ou subóxidos são também descritos bem como capacitorescontendo anodos feitos dos óxidos e subóxidos de nióbio.
