| Abstract: | The Ba0.6Sr0.4TiO3 ceramics were prepared by improved electronic ceramics preparing process. The sample was obtained under the optimalized sintering temperature 1 340 ℃.The density could reach 98.3% of the theoretical density. At room temperature, the dielectric loss of the sample was 0.2%. The effects of DC field on the material's dielectric and pyroelectric property was obvious. The pyroelectric coefficient of the sample was 3.4×10-8 C/cm2·℃, the figure of merit of the sample was 10.0×10-5 Pa-1/2. |
