Abstract

Methods of producing zirconium oxide compositions and using same are provided. The zirconium oxide compositions in crystalline form can be prepared by a synthetic process wherein the hydrolysis of zirconyl chloride and particle formation can be achieved simultaneously. Alternatively, the particle formation can occur first and then followed by hydrolysis with a base solution. The processes utilize a zirconyl salt solution that includes a zirconyl salt in isopropanol and water.
