Crystal Structure and Electrical Characteristics of (0.965)(Li0.03(Na0.5K0.5)0.97)(Nb1−xSbx)O3−0.035(Bi0.5Na0.5)0.9(Sr)0.1ZrO3 Ceramics Doped with CuO, B2O3, and ZnO

Recently, the need has arisen to enhance piezoelectric properties and temperature stability of (Na,K)NbO3 system ceramics. The (0.965)(Li0.03(Na0.5K0.5)0.97)(Nb1−xSbx)O3−0.035 (Bi0.5Na0.5)0.9(Sr)0.1ZrO3 ceramics were newly manufactured using sintering aids CuO, B2O3, ZnO as a function antimony substitution, their crystal structure electrical characteristics analyzed. grain size was apparently refined amount increased. dielectric constant enhanced Curie decreased due content substitution. x = 0.07 sample sintered at 1060 °C presented best characteristics, which bulk density 4.488 g/cm3, d33 330 pC/N, electromechanical coupling factor kp 0.427, mechanical Qm 61, εr 2521. We believe that is material for speakers.
