POLYMER, TANTALUM AND NIOBIUM OXIDE CAPACITORS
The Tantalum division of AVX produces a wide range of solid electrolytic capacitors. Typically, the construction consists of a 1st electrode (anode), an insulating layer (dielectric) and a 2nd electrode (cathode) system. The anode is manufactured either from pure tantalum or niobium oxide powder. Tantalum is an element extracted

Niobium | Plansee
Niobium is located in the same period as molybdenum in the periodic table. Its density and melting point are therefore comparable to those of molybdenum. In the same way as tantalum, niobium is prone to hydrogen embrittlement. The heat treatment of niobium therefore takes place in a high vacuum and not in a hydrogen atmosphere.
