Re-fluidising the aged gel for high-density alumina green body
文献摘要:
A green body with a density as high as possible is critical to diminish the crisis of deformation or cracking when large-size parts are sintered.Here,a new method,i.e.,re-fluidising the aged ceramic gel is developed to prepare the high-density green body.Alumina slurry with 56 vol%solid loading and copolymers of isobutylene and maleic anhydride were aged without vaporisation and re-fluidised by non-intrusive shearing after removing the exuded water.The re-fluidised slurry was re-casted.The resultant wet gel was dried and deboned at a low temperature.The relative density of the obtained green body was 64.6%,1.5%higher than that without aging and re-fluidising.The linear sintering shrinkage of the body decreased by 0.7%.The enhanced green density is explained from the viewpoint of the solid loading and the structure of the slurry.
