Abstract: Ultrafine ZrO2 body was prepared by gelation. The effects of PEG solution type, PEG solution concentration and solid loading on desiccation and sintering of ZrO2body were studied in this work. It was proved that PEG aqueous solution could prevent the bodies from cracking and deformation. The dehydration was speeded up with the increase of PEG solution concentration, but decreased with high solid loading. The density and line shrinkage rate of sinteredZrO2body were affected by solid loading, and decreased slightly with its increasing.
Keywords: ultrafine ZrO2 body, gelcasting, desiccation, sintering
