Process for producing a capacitor anode based on at least one of a valve metal and a compound having properties comparable to a valve metal includes providing a pressing or cutting tool which is at least one of made of and coated with a pressing or cutting tool material comprising at least one of a metal carbide, an oxide, a boride, a nitride, a silicide, a carbonitride or alloys thereof, a ceramic material, a hardened steel, an alloy steel, and a capacitor anode material. Particles of the at least one of a valve metal and a compound having properties comparable to a valve metal are pressed or cut with the pressing or cutting tool so as to produce a porous electrode body and form the capacitor anode. |
