摘要：

The　tungsten　bronze　Ba0.5Sr1.5Na0.6K0.4Nb5O15(BSKNN)　ceramics　with　significantly　enhanced　piezoelectric　constants　d15,　from　61.6　pC/N　to　120.0　pC/N　are　prepared　by　CO2laser　irradiation.　The　optimal　process　parameters　are　as　follows:　irradiation　power　density　Pmax=　764.33　W/cm2and　irradiation　time　t　=　90　s.　The　intrinsic　reason　of　the　enhancement　of　the　piezoelectric　properties　is　studied　by　SEM　and　XRD.
