Abstract
Conventional solid state reaction method was employed to synthesize Ba(0.85-x)NdxCa0.15Zr0.1Ti0.9O3(x = 0.000, 0.005, 0.010, 0.015, 0.020, and 0.025 mol%) ceramics. Ceramic samples sintered at 1450 °C were characterized for dielectric, ferroelectric and piezoelectric properties. XRD study confirms the presence of pure perovskite structure in ceramic samples without any secondary peaks, with tetragonal phase from x = 0 to x = 0.015, and cubic phase for x = 0.020 and x = 0.025.The remnant polarization (Pr), room temperature dielectric constant (εrt), piezoelectric coefficient (d33) and electromechanical coupling constant (kp) increase with x and attain the maximum value of 4.3 μC/cm2, 2128, 270pC/N and 0.31 respectively for x = 0.010.
