An improved method of preparing thin film superconducting electrical circuits of niobium or niobium compounds in which a thin film of the niobium or niobium compound is applied to a nonconductive substrate, and covered with a layer of photosensitive material.
Extract Tantalum & Niobium from Pegmatites
This lost tantalum and niobium was considered part of the mica lattice rather than unliberated material. Although a large portion of the mica was removed by coarse screening approximately 10% remained which subsequently caused sizing and separation problems in a gravity beneficiation circuit, so an additional step was incorporated to remove it.
Tantalum capacitor - Wikipedia
A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits.It consists of a pellet of 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 distinguishes ...
