How to select appropriate tantalum capacitors? To choose tantalum capacitors, the first problem is to choose encapsulation, voltage resistance, and capacitance. The capacity determines the size (encapsulation) of tantalum capacitors; on the contrary, what size determines what capacity and pressure tolerance can be achieved.

[en] Tantalum(V) and niobium(V) oxide films, which are typically difficult to prepare by electrochemical methods using aqueous solutions, are easily fabricated in an acetone bath using Ta and Nb anodes as the metal sources and a metal-free solvent containing halide ions as the supporting electrolyte. At the initial stage of electrolysis, anodic oxidation of the metal anode proceeds in the ...

Tantalum is a specialty metal that improves conductivity and is highly resistant to heat and corrosion. AMG has a capacity to produce 300,000 pounds of high purity tantalum oxides (Ta2O5) in concentrates annually. Tantalum is characterized as a bluish-gray metal, and it is extremely ductile and malleable to low temperatures.

Tantalum is a soft, ductile, grey-blue metal with a high melting point. The metal is highly resistant to chemical attack and has a high electrical capacitance. Its physical properties make it ideal for numerous applications, particularly in the electronics and aerospace industries. Tantalum was discovered in 1802 by Anders Gustaf Ekeberg.
