Kurzbeschreibung (Abstract)
Bending strength of commercially relevant lead-free piezoceramics –0.935Na0.5Bi0.5TiO3-0.065BaTiO3(NBT-6.5BT) with and without acceptorZn-doping and 0.92(K0.5Na0.5)NbO3-0.02(Bi0.5Li0.5)TiO3-xBaZrO3;x=0.06,0.07 (KNN-BZ100x) have been quantified using 4-point bending tests andcontrasted to that of commercial lead zirconate titanate (PZT, PIC151). Thecompressive and tensile strength probed using additional strain gauges under4-point bending indicate negligible non-linear deformation, in stark contrastto that of commercial PIC151. The bending strength of KNN-BZ100xis about100 MPa, comparable to PIC151, while that of NBT-6.5BT-based materials isabout twice that of PIC151 at∼160 MPa. These results are rationalized based onthe intrinsic characteristics of the lead-free piezoceramics in terms of fracturetoughness, coercive stress, and Young’s modulus. Weibull statistics indicate ahigher fracture probability for KNN-based materials, with NBT-6.5BT-basedmaterials featuring Weibull modulus twice that of KNN-based materials.
