Electrodeposition of tantalum products in CsCl melt

What is it about?

The electrochemical behaviour and the influence of electrolysis parameters of molten salts systems whith CsCl as solvent for potassium and caesium oxyfluorotantalates are investigated. By doing so, in general several phases crystallize at the cathode simultaneously.

Why is it important?

The most characteristic phases for the melt were two isostructural compounds with pyrochlor type crystal lattice CsTa[2+z](5)O[5+y]F[1−y] and CsTa[2+z](5−x)O[5+y]F[1−y]. The former deposited as of transparent dielectric crystals, the latter as metal-like conductive ones. This latter compound seems to be synthesized for the first time.
