| Abstract: | BaTiO3 based ultra fine powders doped by lanthanium is prepared by sol-gel process using tetrathoxysilance(TEOS), Mg(NO3)2·6H2O and Al(NO3)3·9H2O as raw materials. The structure and compositions of the Ultra fine powders are characterized by XRD,DTA and SEM.The partical sizes are determined to be 40 nm using Scherrer's formula. |
