Abstract
"MéTODO PARA PRODUZIR Pó DE NIóBIO E OUTROS PóS METáLICOS ATRAVéS DE MOAGEM". Métodos para formar pós de nióbio e outros pós metálicos são descritos. O método envolve moer o pó metálico a temperaturas elevadas e na presença de pelo menos um solvente líquido. O método da presente invenção têm a capacidade de reduzir a fuga de corrente contínua e/ou aumentar as capacidades de capacitância dos pós metálicos quando formados dentro de anodos capacitores. A presente invenção também têm a capacidade de reduzir significativamente o tempo de moagem necessário para formar os pós metálicos de alta área de superfície e conduz à redução da quantidade de contaminantes nos pós metálicos. Os pós metálicos tais como os pós de nióbio que possuem quantidade de contaminantes e/ou possuem fuga de corrente contínua reduzidas ou capacidades de capacitância são também descritos. Um processo é também descrito para formar um metal floculado através da moagem em úmido de um pó metálico em um metal floculado onde pelo menos um fluido tratado com flúor líquido está presente durante o processo de moagem em úmido. O processo é particularmente bem adequado para formar flocos metálicos, tais como flocos de nióbio e de tântalo, de alta pureza.
