| 中文摘要 | We investigate the temperature dependence of the dielectric constant of BaTiO3 ceramic with coarse to nano-grain size under different hydrostatic high pressures up to 5000 bar in the range between room temperature and 200 degrees C. The ferroelectric-to-paraelectric phase transition temperatures T-c are determined from the peak of dielectric constant versus temperature. The values of average grain-size are estimated from the SEM images. It is found that the magnitude of dT(c)/dp varies considerably from sample depending on grain size. The Curie point T-c of the sample grain size decreases more sharply than that of samples with larger one. |
