Abstract

Zirconia-alumina (ZrO2Al2O3) powders have been prepared by coprecipitation from nitrate solutions with ammonium hydroxide (NH4OH). The particle sizes of the as-precipitated powders, before drying treatment, were found to be 1-10 nm, and the average Brunauer-Emmett-Teller surface area of vacuum dried powders was 170±7 m2 g-1. Experimental results indicate that the NH4OH concentration is the determining factor in controlling the powder morphology. The Al2O3 content of the product seems to predominate over the pH value in affecting the ZrO2 powder phase transformation.
