Abstract

La presente invención se refiere a polvos aglomerados de metal de válvula y óxido de metal de válvula que son adecuados particularmente para la producción de capacitores de electrolito sólido, polvos que tienen una gran densidad de esqueleto después de que se sinterizan para obtener cuerpos sinterizados altamente porosos, lo que quiere decir que solamente tienen pocos poros cerrados. Los polvos aglomerados tienen una buena capacidad de compactación y un coeficiente de fricción excelente en función de la superficie específica.
