Abstract：
 A process for preparing nm-class zirconium oxide with controllable size (less than 30 nm) includes preparing two portions of microsuspension containing non-ionic surfactant, n-hexanol, cyclohexane and zirconium salt solution or amminia water, mixing, hydrolysis reaction, centrifuging or filtering, washing with alclohol and water several times, drying and calcining. It features that its size can be controlled by controlling the content of zirconium solution or ammonia water, the ratio of water to surfactant and reaction temp.
