The　bismuth　aluminate　(BiAlO3)　is　a　new　developed　lead-free　piezoelectric　material　with　perovskite　structure.　BiAlO3　has　no　structural　phase　transitions　between　-　133　degrees　C　and　550　degrees　C,　which　indicates　that　it　is　suitable　to　be　applied　in　high　temperature　piezoelectric　device.　In　this　paper,　the　research　progress　and　trends　on　BiAlO3　based　ceramics　are　reviewed　with　emphases　on　the　theoretical　calculation,　high　pressure　synthetic　technology　and　the　addition　of　the　second　compound.　The　limitation　and　problems　in　the　recent　works　are　discussed,　and　some　ideas　for　further　development　of　BiAlO3　based　ceramics　are　suggested.
