| 1 | Effects of Laser Re-heating on Microstructure and Electric Properties of PSN-PZT Ceramics显示文摘Lead zirconate titanate(PSN-PZT) is widely utilized in various areas based on its desirable piezoelectrical properties and stable performance.In order to further improve its electrical properties,the ceramic samples,which have been prepared by traditional solid-state sintering,then are re-heated by strong laser beam.Phase composition and micro-structure have been characterized through XRD,SEM and TEM.Also,Quasi-static d_(33) tester and the capacitance tester have been introduced for measuring electrical performances.The experimental results indicate that the ceramic samples are with more amount percentage tetragonal phase after laser re-heating.Cracks could be induced and initialized by higher input laser intensity.TEM results suggested that,when the input laser power is at 1000 W,tetragonal and rhombohedral phases are co-existed and the ceramic samples are with the best electrical properties.The ceramics heated by power of 1000 W present excellent electric properties,d_(33) increased 24.8%,and tanS decreased 9%,which is distinguish advance compared with original ceramics in solid reaction. | ZHANG Jing ZHENG Deyi PENG Guigui CHENG Cheng HU Shunmin ZHANG Hao | 2016 | Journal of the Chinese Ceramic Society2016，，4： | 0 |
