摘要

It is shown that Ba(ClO4)2 and LiOC2H5 can be used as precursors to form Ba(OC2H5)2. In addition, BaTiO3 ultrafine powders can be prepared by the sol-gel process from Ba(OC2H5)2 and Ti(OC4H9)4. Ethylene glycol added to ethyl alcohol can greatly increase the solubility of Ba(OC2H5)2, and thus the concentration of Ba(OC2H5)2 and Ti(OC4H9)4 can be increased. This leads to a fast sol-gel process for forming BaTiO3 gel. Sol-gel-prepared ultrafine BaTiO3 powders crystallize significantly if heated to 750 degrees C, and crystals fully develop at 900 degrees C. Sol-gel-prepared BaTiO3 powders are ultrafine narrowly distributed in size, and spherical and polyhedral in appearance.
