Tantalum capacitors start with a slug of porous, high surface area tantalum metal with an attached tantalum lead wire. The high surface area contributes to the high capacitance of the capacitor. A thin tantalum pentoxide dielectric is conformally electrochemically deposited on the metal. An intrinsically conductive polymer is deposited on the dielectric. This forms the

The development of tantalum capacitor (TC) industry is associated with the production of one technology metal-tantalum (Ta). The recycling of waste tantalum capacitors (WTCs) is an important strategy for the sustainable development of tantalum related industries.
In this article we evaluated two routes to recover the metal from waste tantalum capacitors. This process involved hammering and physical separation for removal of encapsulated mold resin-a major obstacle in effective tantalum recovery. A complete silica-free tantalum-rich concentrate was obtained containing 89% of tantalum along with other metals.
The effect of electroplating conditions on the electrical properties of the tantalum electrolytic capacitors (TECs) was comprehensively studied. The results demonstrated that incorporating a copper metal layer into the structure of the capacitors significantly reduced the ESR of TECs.
Increasing pressure on consistent supply is a growing concern for user industries. Waste tantalum capacitors as a secondary resource, may help to conserve the natural resources and minimize the waste generation if processed efficiently.
In 1956, H.E. Haring and R.L. Taylor from Bell Labs designed the first generation of solid tantalum electrolytic capacitors, which utilized tantalum pentoxide (Ta 2 O 5) as the dielectric layer, manganese dioxide (MnO 2) as the cathode material, and graphite silver paste as the auxiliary cathode layer .
This kind of capacitor had a high capacitance density, good low-temperature performance, and long service life, and was widely used in various electronic devices. However, solid tantalum electrolytic capacitors with MnO 2 still have several drawbacks. Firstly, the use of MnO 2 with high resistance makes it have a high ESR.
