中文摘要：

采用电泳沉积方法制备陶瓷薄膜过程中，陶瓷颗粒分散良好的稳定悬浮体系是获得高质量薄膜的关键。La2Mo209在800℃具有较高的离子电导率，在中温固体氧化物燃料电池中有潜在应用价值。本文采用柠檬酸盐法制备了粒径约为150nto的如Mo2O9粉体。通过ζ电位的测量，确定了稳定的悬浮体系中丙酮、水、h和La2M0209粉体的含量，采用电泳沉积方法在La0.8Sr0.2CoO3-x基体上制备了La2Mo2O9薄膜。

英文摘要：

To obtain high quality ceramic films by electrophoretic deposition （EPD） method, a supension system with well dispersed ceramic powders is very important. La2Mo2O9 has potential application in intermediate temporature solid oxide fuel cells （IT SOFC） for its high ionic conductivity at 800℃. La2Mo2O9 powders with the size about 150nm in dianreter were synthesized by the citrate - gel method. ζ potential , a parameter to charactrize the stability of a suspension system, was used to determine the concentration of acetone, water, 12 and La2Mo209 powder. La2Mo2O9 films were fabricated on La0.8Sr0.2CoO3-x substrate by means of EPD method.
