Abstract
La presente invención se sitúa en el campo de la ingeniería de materiales y la nanotecnología. Más concretamente, la invención describe un preparado de nanopartículas de niobio, su uso y un proceso de obtención por conminución, es decir, un proceso top down. La invención es un logro que hasta la fecha se consideraba inalcanzable, ya que durante décadas se intentó, sin éxito, obtener nanopartículas de pentóxido de niobio de gran pureza y en grandes cantidades. Lo preparado de nanopartículas de la invención resuelve estos y otros problemas y tiene una composición, pureza, perfil de tamaño de las partículas y área superficial específica peculiares y es útil en una variedad de aplicaciones. La invención también revela un proceso para la obtención de nanopartículas de especies minerales que contienen Niobio, mediante conminución controlada y sin reacciones químicas o contaminaciones con reactivos típicos para la síntesis de nanopartículas. La presente invención, en amplio contraste con el estado del arte, prevé la obtención a gran escala de nanopartículas de pentóxido de niobio con elevada pureza, perfil de tamaño de las partículas determinado y área superficial específica muy elevada, lo que hace factible en la práctica su utilización en diversas aplicaciones industriales.
