Fine yttria-stabilized zirconia powders were prepared by the spray pyrolysis of aqueous solutions of ZrOCl{sub 2} {center dot} 8H{sub 2}O and Y(NO{sub 3}){sub 3} {center dot} 5H{sub 2}O (3 mol%). An appropriate thermal treatment resulted in slightly porous spherical particles with a narrow size distribution. The sintering ability of these powders is evaluated.
