| Abstract: | The influences of the dopants of CaTiO3 and MgTiO3 on the dielectric properties are discussed. The modified materials based on SrTiO3-PbTiO3- Bi2O3·3TiO2 were prepared by doping multiple dopants of MgTiO3, CaTiO3, MnO2, Nb2O5, SiO2. The obtained materials exhibit the properties as follows: dielectric constant εr=1 500～2 000, break down voltage Eb≥12 MV/m and dielectric loss tgδ≤ 6×104. |
