Abstract

"MéTODO PARA PURIFICAR UM COMPOSTO DE NIóBIO E/OU UM COMPOSTO DE TâNTALO ALTAMENTE PURO". Um método de purificação para produzir um composto de nióbio e/ou um composto de tântalo de pureza elevada, caracterizado pelo fato de que compreende a adição de um composto orgânico em uma solução aquosa possuindo, dissolvido na mesma, um composto de nióbio e/ou um composto de tântalo contendo impurezas, e depois sujeição da mistura resultante a um tratamento de extração. A solução aquosa acima é preferivelmente preparada pelo uso de cristais obtidos pela cristalização de uma solução contendo um composto de nióbio e/ou um composto de tântalo. O método de purificação permite a purificação de um composto de nióbio e/ou um composto de tântalo em um produto de pureza elevada com um procedimento mais simples e mais fácil em um custo reduzido.
