0.36BiScO(3)-0.64PbTiO(3)　(0.36BS-0.64PT)　piezoelectric　ceramics　with　high　Curie　temperature　and　good　piezoelectric　properties　comparable　to　commercial　PZT　ceramics　were　fabricated　through　traditional　solid-state　reaction　method.　Microstructural　morphology,　phase　transition,　and　electrical　properties　of　0.36BS-0.64PT　ceramics　were　investigated　systematically.　A　high　temperature　single　element　ultrasonic　transducer　was　designed　and　fabricated　using　this　ceramic.　The　temperature　stability　of　the　piezoelectric,　and　acoustic　properties　of　the　transducer　was　investigated　in　detail.　It　was　found　that　the　0.36BS-0.64PT　based　transducer　can　maintain　reasonably　good　performance　at　temperatures　as　high　as　200　degrees　C.　The　center　frequency　was　found　around　4　MHz　and　changed　slightly　with　the　temperature　from　30　degrees　C　to　200　degrees　C.　The　-6　dB　bandwidth　was　found　over　12%　at　200　degrees　C.　The　results　show　that　the　0.36BS-0.64PT　ceramics　have　great　potential　for　high-temperature　ultrasonic　transducer　applications.　(c)　2018　Elsevier　B.V.　All　rights　reserved.
