Abstract
(Pb, La)(Zr, Ti)O3 films were prepared by multiple (electro-phoretic deposition/sintering) cycles, using fine crystalline powders, acetone, nitrocellulose and HNO3 as suspensions. Dense, strong films having a final thickness of 15∼25 µm were formed reproducibly on platinum substrates. Due to tight contact between the film and rigid substrate, during firing, lattice constants of sintered films were 0.3∼0.5% longer than those of bulk with the same composition. Reflecting these lattice expansions, the Curie temperature of sintered films shifted to higher temperature as compared to that of bulks with the same composition. All films with the composition 8/65/35 and 9/65/35 are ferroelectric and thus exhibit pyroelectric, and piezoelectric activities. These characteristics of the films are modified from those of the bulk form by crystal lattice distortion.Keywords
