“…Tape casting slurries are expected to present a shear-thinning behavior to produce films with a homogeneous and smooth surface. A slip with shear-thinning behavior decreases its viscosity under the shear rate produced by the blade, and after passing through the blade, the shear rate is released and the viscosity increased [17,18]. Nevertheless, some compositions could not avoid generating defects in the final green tape after drying, such as cracks and bubbles.…”

Aqueous tape casting was used to produce yttria-stabilized zirconia films for electrolyte-supported solid oxide fuel cell (SOFC). Tape casting slurries were prepared varying the binder content between 20 and 25 wt%. A commercial acrylic emulsion served as binder. Rheological measurements of the two slurries were performed. Both slurries showed a shear-thinning behavior. Tapes with 25 wt% binder exhibited adequate flexibility and a smooth and homogeneous surface, free of cracks and other defects. Suitable conditions of lamination were found and a theoretical density of 54% in the laminates was achieved. Laminated tapes showed higher tensile strength compared to single sheets. Tape orientation has a significant influence on the mechanical properties. Tensile strength, elongation to strain, and Young’s modulus measured in samples produced in the direction of casting showed higher property values.

“…The binder is of particular importance. It could be based either on water or a non-aqueous solvent [147][148][149][150][151][152][153][154][155][156][157]. Aqueous slips are cheap, non-flammable, and less toxic but they require more energy and time to get dry.…”

Ceramic matrix composites reinforced with carbon nanotubes are becoming increasingly popular in industry due to their astonishing mechanical properties and taking into account the fact that advanced production technologies make carbon nanotubes increasingly affordable. In the present paper, the most convenient contemporary methods used for the compaction of molding masses composed of either technical ceramics or ceramic matrix composites reinforced with carbon nanotubes are surveyed. This stage that precedes debinding and sintering plays the key role in getting pore-free equal-density ceramics at the scale of mass production. The methods include: compaction in sealed and collector molds, cold isostatic and quasi-isostatic compaction; dynamic compaction methods, such as magnetic pulse, vibration, and ultrasonic compaction; extrusion, stamping, and injection; casting from aqueous and non-aqueous slips; tape and gel casting. Capabilities of mold-free approaches to produce precisely shaped ceramic bodies are also critically analyzed, including green ceramic machining and additive manufacturing technologies.

“…Commercially available low cost binders based on acrylate copolymer obtained carboxyl group and polyvinyl butyral were chosen by the aqueous/ non-aqueous processing, respectively [6,20]. The preparation conditions are adjusted on the E_YSZ and implemented with the small variety for the W_YSZ.…”

“…The ceramic suspension consists of the oxide/non-oxide ceramic powder, solvent, dispersant, de-foaming agent, binder and plasticizer. Dispersants ensure the homogeneity of the suspension [5], binders and plasticizers are incorporated mainly for strength and flexibility of the green tape [6][7][8]. De-foaming agents are added to prevent formation of air bubbles in the suspension during the mixing process.…”
