Abstract: The nanocrystalline ZrO2·3%Y2O3 powders with a tetragonal phase were hydrothermally synthesized from Zr(OH)4·3%Y(OH)3·nH2O using 2-methoxyethanol-water solution as the media. The effects of the constituents of media, pH and reaction temperature and time on ZrO2·3%Y2O3 particles were investigated. The results indicate that pHof the media are different due to the various constituents of the media. The higher the 2-methoxyethanol content, the lower the agglomeration of the primary particles. The higher the reaction temperature, the smaller the particles. The anions such as Cl-, NO3- and SO42- have an important impact on the product particles.
