Tantalum Processing TIC

Tantalum metal powder, including the precursor to capacitor grade powder, is generally produced by the sodium reduction of the potassium tantalum fluoride in a molten salt system at high temperature. The metal can also be produced by the carbon or aluminium reduction of the oxide or the hydrogen or alkaline earth reduction of tantalum chloride.

Tantalum—processing, properties and applications

1989-10-1  Tantalum— the Earth’s 49th most abundant element— is frequently produced as a by-product of tin smelting. The metal is also extracted from concentrates by reduction with sodium or fused-salt electrolysis; tantalum carbide is produced by carburization of Ta 2 O 5 or tantalum hydride. Sintering, electric-arc melting and electron-beam melting are used to refine and purify raw tantalum.

Tantalum Processing Equipment, Process Flow, Cases

Tantalum is recovered from ore minerals such as columbite and tantalite that are mined in open pits and underground.

Another is that tantalum ore from Central Africa is Class 7, which makes transport more complicated and expensive. A processed product would not be Class 7 (although the processing waste retained in Africa would still be mildly radioactive). A third benefit is that processing ore would help the local economy.

Tantalum Alloys in Chemical Processing: CPI Through

Tantalum alloys continue to fill a niche in applications where long-life, reliability, maintenance-free and rapid heat transfer are required. Tantalum alloys owe their exceptional corrosion resistant properties to a thin surface layer of tantalum oxide (Ta 2 O 5) that forms on the metal’s surface when exposed to oxygen.
