Polyacrylamide type flocculants have been used in the secondary removal of silicon in preparation of high-purity zirconium oxychloride. Under optimum conditions of the process 98.9% and more silicon was removed and the silicon content in final product was ≤0.0005%.
- high-purity zirconium oxychloride,
- silicon removal,
- polymeric flocculant,
- polyacrylamide
