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

本文介绍了通过压滑铸造（PSC）方法形成的用于透明零件制造的YAG和尖晶石生坯的实验数据及其解释。基于过滤动力学的模型，确定了最佳操作条件。结果表明，该方法能够通过确保滤饼的孔隙率表现出较低的平均尺寸和窄的尺寸分布而提供高度可烧结的生坯。将结果与其他流行的成型方法（如滑模铸造（SC）和冷等静压（CIP））进行了比较。就获得高烧结性生坯而言，发现PSC优于其他方法。对于YAG，
