(Pb以超细晶粉末、丙酮、硝酸纤维素和硝酸为悬浮液，采用多次电泳沉积/烧结工艺制备了（Zr，Ti）O3薄膜。 在铂衬底上可重复地形成最终厚度为15 μ m-约25 μ m的致密、坚固的膜。 由于薄膜与刚性基体之间的紧密接触，在烧结过程中，烧结薄膜的晶格常数比具有相同组成的块体的晶格常数长0.3约0.5%。 反映这些晶格膨胀，居里温度的烧结膜转移到更高的温度相比，具有相同的组合物的散装。 所有薄膜的组成为8/65/35和9/65/35是铁电的，因此表现出热电和压电活动。 薄膜的这些特性是通过晶格畸变从块状形式的那些特性修改的。
(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 approximately 25-mu-m 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 approximately 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.
