In　this　work,　we　fabricated　the　(1-x)BiFeO3-xBaTiO(3)+y　parts　per　thousand　mol　CuO　ceramics　by　the　modified　thermal　quenching　technique.　The　pure　perovskite　phase　was　formed　and　a　morphotropic　phase　boundary　(MPB)　was　observed　in　the　ceramics　with　x=0.30-0.33.　The　addition　of　CuO　can　significantly　enhance　the　density　of　the　BiFeO3-BaTiO3　material.　Importantly,　an　enhanced　piezoelectric　constant　(d(33)=165　pC/N),　a　large　electric-field-induced　strain　(S=0.54%:　peak　to　peak　strain)　and　a　large　piezoelectric　actuator　constant　(d(33)*=449pm/V)　together　with　a　high　Curie　temperature　(T-C)　of　503　degrees　C　were　observed　in　the　ceramics　with　x=0.30　and　y=5.　As　a　result,　the　enhanced　piezoelectricity　and　large　electric-field-induced　strain　could　significantly　stimulate　further　researches　in　BFO-based　ceramics.
