Abstract

PREPARADO DE NANOPARTÍCULAS DE NIÓBIO, USO E PROCESSO PARA SUA OBTENÇÃO. A presente invenção descreve um preparado de nanopartículas de Nióbio, seu uso, e um processo para a sua obtenção por cominuição, ou seja, um processo top down. O preparado de nanopartículas da invenção resolve estes e outros problemas e tem composição, pureza, perfil granulométrico e área superficial específica peculiares, sendo útil em uma variedade de aplicações. A invenção também revela um processo para a obtenção de nanopartículas de espécies minerais contendo Nióbio, mediante cominuição controlada e sem reações químicas ou contaminações com reagentes típicos da síntese de nanopartículas. A presente invenção, em amplo contraste ao estado da técnica, proporciona a obtenção em larga escala de nanopartículas de pentóxido de Nióbio com elevada pureza, perfil granulométrico determinado e muito elevada área superficial específica, viabilizando na prática seu uso em diversas aplicações industriais.
