Abstract

"MéTODO PARA PURIFICAR UM COMPOSTO DE NIóBIO E/OU UM COMPOSTO DE TâNTALO". Um método para purificar um composto de nióbio e/ou um composto de tântalo, caracterizado pela cristalização do composto de nióbio e/ou do composto de tântalo de uma solução dos mesmos. No método de purificação, exemplos de composto de nióbio e/ou de composto de tântalo incluem óxidos de nióbio e/ou óxidos de tântalo. Exemplos de solvente incluem ácido fluorídrico, especialmente um possuindo um teor de água de 80% em peso ou menor. Assim, um composto de nióbio e/ou um composto de tântalo podem ser facilmente purificados em custo baixo.
