Abstract: Flexible setter powder deposition sheets containing setter powders were developed for sintering of ceramic articles including tapes by an economical, fast and simple method. The sheets provide for deposition of a thin and uniform layer of setter powders on a green ceramic article after burnout of a binder in the sheet. Because of high strength and low burnout temperature, hydroxypropyl methylcellulose binder is preferred for production of these sheets. Tape cast sheets with low solids loading can be obtained by optimizing the wetting behavior of aqueous slurries on tape carrier. Setter, powder deposition sheets are of particular benefit in processing of thin ceramic tapes, particularly for processing of piezoelectric ceramic tapes. Tapes can be processed in a sandwich formed by layering setter powder deposition sheets between tapes and cover plates employed to maintain tape flatness and to reduce evaporation of volatile components of the ceramic.
