Study on the Preparation of Stabilized Ultrafine Zirconia Powders by Using Reverse Micellae

Abstract

Abstract: The solubilization behavior of metal ions and ammonia solution in AOT-isooctane-water reverse micelles was investigated by injection method, the size of reverse micelles
was then determined with dynamic light scattering technique, and the microstructure of reverse micelles containing metal ions was characterized by using freeze
fracture electron microscopic technique. With these micellar solutions, Y₂O₃ and CeO₂ stabilized ultrafine zirconia powders were prepared accordingly. Different kinds of preparative
manners were tried to examine their effects on the quality of powders thereby derived. It was found that the swollen of metal ions in reverse micelles was an essential
condition for obtaining a powder with good quality.

Key words: reverse micelles, microstructure, stabilized zirconia, ultrafine powder
