Abstract: The nanosized BaTiO3powders modified with a layer of stearic acid were successfully prepared through the hydrothermal method and their microstructures were characterized. The results indicate that the products are of small crystal with small grain-size, narrow grain-size distribution and little agglomeration, meanwhile the polarity of the nanometer BaTiO3particles was greatly reduced and the powders had a better flowability. Because the surface of the nanometer BaTiO3powders was modificated with a layer stearic acid , which weakened the interaction between the particles of the powder.
