摘要：

Barium titanate thick films 10-70 mum thick were obtained using a unique electrophoretic deposition technique, which utilizes a mixed ethanol-acetylacetone suspension as the dispersive medium. The capacitance of the BaTiO3 films was measured as 25-70 nF, at temperatures of up to 200-degrees-C, giving a dielectric constant of 4000-12000 and dielectric loss (tan delta) of 0.13-0.51. In the sintered films thus deposited, (111) orientation was observed, and the degree of orientation was found to increase with decrease of the thickness of the films. In so-oriented films, the Curie point was confirmed to be near 120-degrees-C.
