主　　题：PSN-PZT ceramics laser re-heating electrical properties 

摘      要：Lead zirconate titanate(PSN-PZT) is widely utilized in various areas based on its desirable piezoelectrical properties and stable *** 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 *** composition and micro-structure have been characterized through XRD,SEM and ***,Quasi-static d_(33) tester and the capacitance tester have been introduced for measuring electrical *** experimental results indicate that the ceramic samples are with more amount percentage tetragonal phase after laser *** could be induced and initialized by higher input laser *** 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 *** 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.
