The present study examined whether the optimum slurry conditions in which the green body with the highest packing fraction was fabricated were the same regardless of whether tape or slip casting methods were used. Additionally, we investigated the optimum slurry evaluation method to predict the packing fraction of each green body. Specifically, aqueous dense alumina slurries, whose particle dispersion state was changed by varying pH and the amount of dispersant additive, were prepared. After changing the pH, the optimum slurry conditions were achieved regardless of the casting method. The most suitable amount of additive dispersant differed due to the changing solution conditions during the casting and drying process; the medium of the slurry permeated into the plaster during slip casting and dried on the substrate during tape casting. Thus, in slip casting, non-adsorbed polymers could also be permeated. Hence, it is crucial for slurry evaluation to predict the packing fraction of the slip cast body. A sedimentation test, which involved particle condensation as well as casting, was valid for the green sheet. Conversely, it was experimentally shown that the constant pressure filtration test, which involved the permeation of the medium in addition to particle condensation, was suitable for slip casting. 相似文献

The tape casting process for manufacturing low‐temperature co‐fired ceramic green sheets: A review 下载免费PDF全文
For low‐temperature co‐fired ceramic technology, the fabrication of high‐performance green sheet is a critical step because of its effect on subsequent operations such as punching, printing, laminating, and firing. Here, we present an overview of the tape casting process for manufacturing high‐performance low‐temperature co‐fired ceramic green sheets. Previous research is reviewed, and the primary materials for preparing the casting slurry, such as powders, solvents, dispersants, binders, and plasticizers, are systematically described. Their functions, application methods, and action mechanisms are described. Suggestions are made for future research into the tape casting process based on recent results. 相似文献
