摘要：

The Ba0.3Sr0.6Ca0.1TiO3 (BSCT) powder was prepared through the solid-state reaction. And then preparing ceramic samples with quantitative doped-Bi2O3.3TiO(2) and different doped-MgO. X-ray diffractometer (XRD) and scanning electron microscopy (SEM) were used to investigate the phase compositions, distribution and morphology of the ceramic samples. SM-11J49 capacitance measurement instrument and CS2674A pressure tester were used to measure the dielectric properties of the samples. The results show that the compactness and the dielectric constant of the ceramics increases first and then decreases when the doped MgO content was changed from 1.5 to 4.5 wt.%. The trend of breakdown strength is characterized by M-shaped pattern with the increase of doped-MgO content. Calculation results demonstrate that when the doped-MgO content is 2.0%, the samples have the highest energy storage density.
