摘 要：Polycrystalline SrBi_(4)Ti_(3.975)Zr_(0.025)O_(15)(SBTZ)was prepared using solid-state reaction *** was characterized by X-ray diffraction(XRD)and scanning electron microscopy(SEM).XRD analysis indicated the formation of a single-phase orthorhombic *** size was found using *** dielectric,ferroelectric,piezoelectric,modulus and impedance spectroscopy studies on SBTZ were investigated in the frequency range 1Hz-1MHz from room temperature(RT)to 600℃.Piezoelectric charge and electromechanical coupling coefficients were calculated from resonance and anti-resonance *** and modulus plots were used as tools to analyze the sample behavior as a function of ***-Cole plots showed a non-Debye *** measurements were performed on SBTZ.
