摘要：

Lead-free　0.85(Bi1/2Na1/2)TiO3-0.10(Bi1/2K1/2)TiO3-0.05BaTiO(3)　(BNKBT)　ceramics　with　Li2CO3　or　(Bi1/2Li1/2)TiO3　(BLT)　added　were　fabricated　by　conventional　solid　oxide　route.　The　XRD　analysis　indicated　that　Li2CO3　introduction　led　to　increasing　fraction　of　tetragonal　phase　while　BLT　introduction　gave　a　reverse　tendency.　Meanwhile,　the　depolarization　temperature　T-d　of　Li2CO3-added　BNKBT　ceramics　was　clearly　enhanced,　while　that　of　BLT-added　BNKBT　ceramics　went　down　as　the　added　amount　increased.　The　similarity　in　variation　of　the　phase　structure　and　the　T-d　of　BNKBT　ceramics　revealed　the　nature　of　the　Li+　introduction　source　on　phase　structure　in　BNKBT　ceramics.　(C)　2010　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
