Abstract
"óXIDO DE NIóBIO DE REDUZIDO TEOR DE OXIGêNIO". Métodos para reduzir pelo menos parcialmente de nióbio são aqui descritos onde o processo inclui o tratamento térmico do oxido de nióbio em presença de um material metálico absorvedor de gás e em uma atmosfera a qual permita a transferência dos átomos e oxigênio a partir do óxido de nióbio para o material metálico absorvedor de gás, e durante um período suficiente de tempo e a uma temperatura suficiente para formar um óxido de nióbio de reduzido teor de oxigênio. Os óxidos de nióbio e/ou sub-óxido são também descritos bem como anodos contendo capacitores produzidos a partir de óxidos de nióbio e sub-óxidos. Anodos formados a partir de pós de óxido de nióbio usando aglutinantes e/ou lubrificantes são descritos bem como métodos para formar os anodos.
