Abstract

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.
