A capacitor is comprised of an anode and a cathode separated by a dielectric. In the case of a tantalum capacitor, the anode is tantalum powder, the cathode is a conductive or semi-conductive material, and the dielectric is tantalum pentoxide (Ta2O5) formed on the surface of the tantalum powder.
The flowability and formability depend on the bulk density of the powder, the particle size distribution, the cohesion strength of agglomerated powder, etc., and are greatly affected by the conditions of the tantalum capacitor grade powder manufacturing process.
They ground metallic tantalum to a powder, pressed this powder into a cylindrical form and then sintered the powder particles at high temperature between 1,500 and 2,000 °C (2,730 and 3,630 °F) under vacuum conditions, into a pellet ("slug"). These first sintered tantalum capacitors used a liquid electrolyte.
Tantalum capacitors are reliable components. Continuous improvement in tantalum powder and capacitor technologies have resulted in a significant reduction in the amount of impurities present, which formerly have caused most of the field crystallization failures.
The original wet tantalum capacitors developed in the 1930s were axial capacitors, having a wound cell consisting of a tantalum anode and foil cathode separated by a paper stripe soaked with an electrolyte, mounted in a silver case and non-hermetic elastomer sealed.
Increasing capacitance depends on the dimensions and physical properties of the dielectric layer. In tantalum capacitors, capacitance (C) is directly proportional to the specific surface area (SSA) of the Ta2O5 dielectric layer of the tantalum pellet.

A typical tantalum capacitor is a chip capacitor and consists of tantalum powder pressed and sintered into a pellet as the anode of the capacitor, with the oxide layer of tantalum pentoxide as a dielectric, and a solid manganese dioxide electrolyte as the cathode.
