ore processing zirconium


Making Zirconia by Zirconium Chlorination

Another process for the preparation of highly pure ZrO2 – 99.8% from the collected ZrCl4 is also performed by dissolving the zirconium tetrachloride in water, forming the zirconyl chloride which crystallize in the form of ZrOCl2.8H2O, by either evaporation of the solution or by increasing the acidity by additions of hot hydrochloric acid.
