A solid tantalum capacitor consists of a sintered anode with an oxide formed throughout its body, creating tantalum pentoxide as the dielectric. Then, a magnesium dioxide (MnO2) or polymer system is applied to form the cathode. The formation of the anode slug for a wet tantalum capacitor is done in much the same way as the solid tantalum capacitor.

Finally, the pellet used in solid tantalum capacitors is dipped into graphite and silver to provide a good cathode connection. In contrast to solid tantalum capacitors, wet tantalum capacitors use a liquid electrolyte.
