Ethanol-based Tape Casting Process of the Textured Bi0.5(Na0.80K0.20)0.5TiO3-BiFeO3 Ceramics

The rheological and tape casting behavior of ethanol-based Bi0.5(Na0.80K0.20)0.5TiO3-7 mol% BiFeO3 (BNKT-BF) slurries was investigated. The effect of sintering temperature profile on texture development with a preferred orientation was also studied. A 50 MPa pressure assisted three step sintering profile promoted extensive texture development together with densification. The role of BF as a sintering promoter has been discussed.
