Product Description

Tantalum bars are a vital component material across a range of industries, with applications in medicine, industry and high-performance alloy production thanks to its remarkable traits – both chemical and physical. One of these traits is an extreme resistance to corrosion, which makes tantalum perfect for use in highly caustic environments in chemical industry and marine applications, and for use in alloys and coatings.

As a metal powder, the primary application of tantalum is in the manufacture of electronic parts, especially capacitors and some high-power resistors. Tantalum electrolytic capacitors exploit the propensity of tantalum to form a surface layer of protective oxide, using tantalum powder, pressed into a pellet shape, as one "plate" of the condenser, the dielectric oxide, and the other "plate" as an electrolytic solution or conductive solid. Since the dielectric layer can be very thin (thinner than the equivalent layer in an aluminium electrolytic capacitor, for instance), a small volume of high capacitance can be achieved.
