Lead-free, bismuth sodium titanate-potassium sodium niobate piezoelectric ceramics (Bi1/2Na1/2)TiO3-(K 1/2Na1/2)NbO3 have been prepared by a conventional mixed-oxide method via vibro-milling technique. The (K 1/2Na1/2)NbO3 (KNN)-based compositions with a morphotropic phase boundary (MPB) have shown...
