Tantalizing tantalum.
Element 73 was first extracted from mineral samples and described in 1802 by the Swedish chemist Anders Ekeberg. He chose the name tantalum because “when placed in the midst of acids it is incapable of taking any of them up and saturating itself with them”, in a manner reminiscent of the Greek mythological king Tantalus (pictured) who couldn’t eat or drink anything despite being surrounded by f...
متن کاملPorous tantalum and tantalum oxide nanoparticles for regenerative medicine.
For centuries, inflammatory/foreign body reactions have plagued the attempts of clinicians to use metals for tissue and bone reconstructions. Since corrosion contributes to the rejection of metal by the body, an extremely bioinert metal - tantalum - has been successfully used in medicine. The outstanding biocompatibility and flexibility of tantalum established the basis for a growing cadre of c...

متن کاملReliability Effects with Proofing of Tantalum Capacitors
In traditional tantalum capacitors, the construction consists of a tantalum anode, Ta2O5 dielectric, and MnO2 as the cathode. The benefit of having MnO2, as the cathode, is the self-healing effect it provides. The conversion of MnO2 to a higher resistive state allows fault sites within the dielectric to be shut off from the rest of the capacitor. To mitigate problems developed during reflow, it...
متن کاملCharacterization of Tantalum Polymer Capacitors
Solid-electrolyte tantalum capacitors were first developed and commercially produced in the 1950s. They represented a quantum leap forward in miniaturization and reliability over existing wound-foil wet electrolytic capacitors. While the solid tantalum capacitor has dramatically improved electrical performance versus wet-electrolyte capacitors, especially at low temperatures, today’s electronic...
