A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits. It consists of a pellet of porous tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode. Because of its very thin and relatively high permittivity dielectric layer, the tantalum capacitor distinguish…

Tantalum Powder

Sodium reduction of potassium fluotantalate is an important process for the production of capacitor-grade tantalum powder and the main process for the industrial production of metal tantalum powder. Before the 1950s, solid sodium metal and potassium fluotantalate were placed in layers in a bomb reactor for explosive reduction reaction.
