    Abstract

    In this manuscript, we report the variation of piezoelectric constant (d33) at room temperature in (K0.5Na0.5) NbO3 (KNN) based ceramics. Phase fraction and orthorhombic to tetragonal phase transition temperature (TO-T) were found to be the controlling variables of piezoelectricity. Using the model system of (1-x)K 0.48Na0.48Li0.04)NbO3-xBaTiO 3 [(1-x)KNLN-xBT] and 0.99(K0.48Na0.48Li 0.04)(Nb1-ySby)O3-0.01BaTiO 3 (KNLN1-ySy-BT), it is shown that maximum d33 magnitude for KNN based polycrystalline ceramics is approximately 300 pC/N at room temperature.
