Transparent ceramics green-microstructure optimization by pressure slip-casting: Cases of YAG and MgAl2O4

This paper presents experimental data and its interpretation regarding the forming of YAG spinel green-bodies, intended for transparent parts fabrication, by pressure slip casting (PSC) method. Conditions an optimal operation are established based on modeling filtration kinetics. It emerges that method is able to provide highly sinterable green ensuring cakes porosity exhibits low average size narrow distribution. Results were compared with other popular approaches like (SC) cold isostatic pressing (CIP). PSC was found as superior, approaches, far obtainment high sinterability green- bodies concerned. In case YAG, it shown even allows replacement traditional long vacuum firings a two stage densification in which initial air-firing completed hot step.
