Abstract: Ingot-derived and sodium-reduced agglomerated tantalum powders having improved flow characteristics and lead pull-out strength that find particular utility in manufacture of anodes for capacitors. Powder size distribution is in the range of -60 to +400 mesh, preferably -60 to +250 mesh, containing less than 5 wt % powder above the upper and below the lower range limits.
