摘　　要：研究了掺杂1%和2%纳米钛酸钡后钛酸钡陶瓷的表面形貌和介电性能。结果表明,掺杂纳米钛酸钡对陶瓷的介电性能有显著的提高,掺杂1%和2%纳米钛酸钡对陶瓷介电性能的变化不大。钛酸钡薄膜的最佳成膜工艺为:乙酰丙酮-乙醇的混合溶液浓度为75 g/L,直流电压为50 V,电泳时间5 min。The surface morphologies and dielectric properties of the barium titanate ceramic were investigated after doping 1%- and 2%- nano barium titanate. The results show that the dielectric properties of doped barium titanate are improved greatly, but there is only a little change between the doping amount of 1% and 2%. The best growth process of barium titanate film is that the concentration of mixed solution of acetyl acetone-ethanol is 75 g/L, DC voltage of 50 V and the electrophoresis time is 5 min.
