A separation method of a zirconia/hafnium oxide mixture. Putting the zirconia/hafnium oxide mixture, charcoal and pure bromine into a reaction for one hour under 650℃ to obtain bromide of zirconium and hafnium, adding the bromide of zirconium and hafnium into a molten salt mixture for distillation separation, and keeping a bottom of a distillation tower under 357℃ for two hours to obtain non-target substance; keeping for five hours at 357℃, and collecting high zirconium tetrabromide; saving residues in a kettle; performing distillation separation in a same device, hearting to 400 degrees, keeping for more than five hours to obtain hafnium tetrabromide, and using magnesium to displace the zirconium tetrabromide and the hafnium tetrabromide respectively to obtain pure zirconium and pure hafnium. |
