Studies on the plasmochemical reduction process of niobium and tantalum pentachlorides with hydrogen in arc plasmatrons with an electrical capacity of 15-100 kW resulted in an elaboration of a suitable technological regime for the production of polydispersed nanopowders with an average grain size of 20-150 nm.

To develop an effective process for tantalum powder production, a new preform reduction process (PRP) based on the magnesiothermic reduction of feed preform containing tantalum oxide (Ta 2 O 5 ) was investigated. The feed preform was fabricated from slurry, which was made by mixing Ta 2 O 5 powder, flux (e.g., CaCl 2 ), and binder.

The process for anealing tantalum is to heat the material n a high vacum to temperatures above 2000 degree F. Corrosion Resistance. Tantalum is known for it's excellent corrosion resistance to most acids. Similar to glass, one of the few exceptions is hydrofluoric acid. Any solution containing the fluoride ion should be avoided.

A large number of passivation cycles needed to surface passivate capacitor grade tantalum powders increases production time, costs and complexity. Furthermore, tantalum powders have been acid leached for the removal of the getter material(s) used in an earlier deoxidation step included in the process flow.
