摘要：

By　using　two-stage　sintering　method　based　on　the　traditional　process　equipment,　one　lead　free　piezoelectric　ceramics　Sr2-xCaxNaNb5O15　(SCNN)　was　prepared.　By　studying　the　different　Sr　doping　concentrations　x　from　0.05　to　0.30,　piezoelectric　constant　is　up　to　80　pC/N,　and　dielectric　permittivity　is　even　more　than　1600.　This　SCNN　ceramics　are　characterized　by　X-ray　diffraction　and　scanning　electron　microscope.　Results　show　that　this　ceramics　have　high　density　structure.
