Abstract

"MéTODOS DE PRODUçãO DE UM óXIDO DE METAL NIóBIO". Métodos para reduzir pelo menos parcialmente um óxido de nióbio são descritos. Em uma modalidade, um processo de moagem é descrito onde as superfícies do moinho em contato com o óxido metálico inicial, material absorvente, e/ou óxido metálico reduzido com oxigênio são do mesmo material do material que está sendo moído. Outras técnicas de moagem e produtos são também descritos.
