Abstract
The production of highly porous sintered bodies useful for the manufacture of electrolytic capacitors by using as a lubricant for the base metal powder, usually tantalum, about 0.01 to about 10% by weight of an inorganic lubricant, particularly a sulfide, selenide or telluride of a metal of subgroup V or VI of the Periodic Table or nitrides of boron or silicon.
