The rheological behavior and tape-casting performance of ethanol-based Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) slurries is studied. A nanocrystalline powder obtained by mechanochemical activation was used. Suspensions were prepared up to solid contents of 32 vol%; significantly higher than those usually reported for nonaqueous systems. The feasibility of replacing toxic solvents commonly used for tape casting of functional ferroelectric materials; often toluene; with ethanol is demonstrated. The density; phases and microstructure of the green tapes and sintered ceramics are presented. Cube-shaped templates were successfully aligned during the tape casting for the processing of 〈001-textured PMN-PT ceramics by templated grain growth. An effect of the lamination of tape stacks on the template orientation is described. © 2009 The American Ceramic Society;
