“…This research is motivated by several reasons. Despite the significant progress, the works devoted to water-based tape casting of the ferroelectrics are still rare [22,23,24]. The method requires a list of different chemicals and reagents, like plasticizers, defoamers, binders and surfactants.…”

The 0.7Pb(Mg 1/3 Nb 2/3 )O 3 -0.3PbTiO 3 ceramic films were prepared using the water-based tape casting method. Two main components of the slurry are water and solids. The concentrations of other chemicals, the surfactant and binder, are at the level of 1 wt. %. Both binder and surfactant are eco-friendly polymers. Additional chemicals are not required. The optimal concentration of surfactant determined through viscosity measurements. The density of the ceramics was studied as a function of the concentration of water and binder. The density is nearly independent of amount of water despite a wide range of values of concentration. This independence is a powerful tool to cast using different techniques. The density substantially depends only on binder concentration. The polymers removal protocol of the cast films was optimized using thermogravimetric analysis. As a result, the translucent ceramic films with a relative density of 98 % and thickness of 70 µm were prepared. The permittivity, remnant polarization and pyrocurrent measurements, along with the scanning electron microscopy, prove the high density of the ceramics.

Transparent Y2.85Yb0.15Al5O12 ceramics were prepared using an aqueous tape casting and vacuum sintering method. The rheological properties were measured by a rheometer. The results indicate high quality tapes, and ceramics can be obtained by increasing the solid loading of the corresponding slurries. The densities of the tapes increase from 2.42 to 2.69 g/cm3 by increasing the solid loadings from 35 to 50 vol%. The corresponding green body densities range from 52.7 to 57.1% of the theoretical. The solid loading suitable for fabricating transparent Yb:YAG ceramics should be higher than 45 vol%.

“…Although higher solid loading and lower porosity are achievable by aqueous tape casting route, the process possesses several technical challenges like slower drying rate, uncontrolled warping during sintering, etc. However, the attractiveness of replacing toxic and expensive non‐aqueous systems by water‐based ones have created a myth of offsetting the above technical challenges and have fueled extensive research in recent years for development of aqueous tape casting systems …”

“…However, the attractiveness of replacing toxic and expensive non-aqueous systems by waterbased ones have created a myth of offsetting the above technical challenges and have fueled extensive research in recent years for development of aqueous tape casting systems. [3][4][5][6][7] Both aqueous and nonaqueous tape casting process requires a well-dispersed suspension of comparatively high solid loading, with reasonably low viscosity, to facilitate the casting of tapes with good handling strength and excellent micro structural homogeneity. [8][9][10][11][12] The dispersion, solid loading, and rheological properties are dependent to a large extent on the interparticle interactions, particle size distribution, and interaction of the particles with the additives.…”

Aqueous Tape Casting Using Organic Binder: A Case Study with YSZ

et al. 2011

Aqueous tape casting of yttria stabilized zirconia (YSZ) having very wide particle size range was investigated using bio‐polymer, gelatin as binder and glycerol as plasticizer. Best dispersion of YSZ powder was obtained by using an anionic polyelectrolyte DARVAN 821A at pH 7.5. Gelling properties of gelatin, plasticized with water and glycerol have been studied by dynamic shear measurements. Decreasing concentration of gelatin significantly decreases the gelling temperature of it. With the addition of optimum amount of binder and plasticizer, it has been possible to prepare stable YSZ suspension of 45–50 wt% solid loading that exhibited the desired shear‐thinning behavior. Green tapes with good flexibility (strain to failure: 12%–24%) and strength (2–3 MPa) with total organics content of 10–14 wt% were obtained. After removal of organics, the tapes were sintered at 1550°C for 3 h. The sintered density of the tapes thus obtained was about 99% of the theoretical density. The grain size of the sintered tape was fairly large (10–20 μm); but the surface of the sintered tape (thickness: 100 μm) did not show any visible porosity.
