| Abstract: | Ba Ti O3ceramics doped with Gd2 O3(the additive content was1% m ol) were prepared by solid- phase method,the crystal structure were studied by SEM and XRD,the dielectric constant,dielectric loss and the resis- tivity of Ba Ti O3ceram ics doped with Gd2 O3were also studied,the dielectric constant was increased obviously,the dielectric loss was also increased,the resistivity was decreased obviously. |

| Keywords: | Ba Ti O3 Gd2 O3 dielectric characteristics |
