A　0-3　type　0.8Na(0.5)Bi(0.5)TiO(3)(BNT):0.2ZnO　lead-free　ferroelectric　composite　ceramic　structure　was　prepared　by　a　solid-state　oxide　route.　The　X-ray　diffraction　analysis　and　scanning　electron　microscopy　observation　indicate　that　ZnO　grains　were　scattered　in　the　matrix　consisting　of　BNT　grains　to　form　a　(0-3)　type　composite　structure,　and　a　third　phase　Zn2TiO4　was　formed　due　to　the　reaction　ability　of　nano-sized　ZnO　with　NBT　compositions.　The　temperature-dependent　electrical　responses　show　that　the　dielectric　anomaly　at　around　200　degrees　C　inherited　from　NBT　itself　was　suppressed　as　ZnO　is　composited,　and　the　P-r　of　the　specimen　sintered　at　1000　degrees　C　keeps　almost　unchanged　as　the　poling　temperature　is　175　degrees　C,　while　its　retained　piezoelectric　strain　d(33)　value　maintains　77%　of　the　initial　as　exposed　to　125　degrees　C　annealing.　These　results　suggest　that　the　thermal　depolarisation　of　BNT　is　suppressed　due　to　the　introduction　of　ZnO,　even　though　the　third　phase　Zn2TiO4　exists.
