Production of low silica-content zirconium dioxide suitable for use in the production of ceramics, fuel cells or catalyst supports, comprises leaching silica from dissociated zirconium silicate using aqueous hydrofluoric acid

摘要

Production of ZrO2 by solvent treatment of thermally-dissociated Zr silicate (optionally SiO2-enriched) uses aqueous HF as the solvent.
