6 FAQs about [Full Tantalum Liquid Tantalum Capacitor Research and Development]

What is the development of tantalum capacitor (TC) industry?

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.

How to recover metal from waste tantalum capacitors?

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.

Can waste tantalum capacitors be used as a secondary resource?

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.

What is a Talum electrolytic capacitor?

Tantalum electrolytic capacitors have been on the market for more than half a century, in a range of applications. However, the most common design uses MnO2 as the electrolyte, which can be thermodynamically unstable and, upon failure, can damage the circuit.

What are the disadvantages of solid tantalum electrolytic capacitors with MNO 2?

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.

Who invented a tantalum electrolytic capacitor?

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 .
