The Synthesis and Application of the NaCl-KCl-K₂HfCl₆ Electrolyte

Abstract:

The NaCl-KCl-K₂HfCl₆ electrolyte successfully prepared by the reaction of HfCl₄ with equimolar NaCl-KCl. Microstructure, surface morphology and components of the electrolyte were analyzed by XRD, SEM, and EDS. The results show that HfCl₄ preferentially reacts with KCl when KCl and NaCl coexist or conversion relationship exist between Na₂HfCl₆ and K₂HfCl₆. The removal rates of oxygen reached 96.98%in electrorefining of hafnium attributed to high stability and low volatility of the electrolyte.
