Plasmachemical Processing of Rare Pefractory Metals Fluoride Solutions

摘要

Fluoride solutions are commonly used for purification and separation of rare refractory metals. Traditional technologies of oxides production from such solutions are rather complicated and ecologically not ideal. Investigations on plasmachemical processing of fluoride solutions containing niobium, tantalum, titanium and zirconium showed the possible oxides (ultrafine powder NbO,TaO, and TiO) and hydrofluoric acid production from these solutions1.2)
