Tantalum Recycling is one of only a handful of companies in the world that has full capability in recycling tantalum based capacitors. Our facility is fully state of the art built exclusively to fully provide Tantalum capacitor scrap recycling in house.
Tantalum Capacitors —
Tantalum electrolytic capacitors exploit the tendency of tantalum to form a non-conductive protective oxide surface layer. This type of capacitor consists of tantalum powder pressed into a pellet shape as one “plate” of the capacitor, with the oxide as a dielectric, and an electrolytic solution or conductive solid as the other “plate”. The dielectric layer thus can be very thin (thinner than the similar layer in, for instance, an aluminum electrolytic capacitor).
The capacitor typically consists of a sintered Tantalum metallic sponge acting as the anode, a manganese dioxide cathode, and a dielectric layer of Tantalum pentoxide heated on the sponge surface by anodizing.
