Abstract
Yttria stabilized zirconia powders (3 mol% in Y2O3) were prepared by t he drying and air-calcination of amorphous gelatinous precipitates obt ained by hydrolysis of solutions containing both zirconium and yttrium acetates. After sintering in air at 1500 or 1600-degrees-C, the chara cteristics of the materials were correlated with certain of the synthe sis parameters (concentration of starting solution and neutralizing ag ent). Cold pressing compaction curves are analysed and the influence o f residual oxycarbonates or carbonates on sintering is discussed
