ABSTRACT Ba(0.85-x)NdxCa0.15Zr0.1Ti0.9O3 (x = 0, 0.005, 0.010, 0.015, 0.020, 0.025) ceramic compositions were synthesized by solid state reaction method. Effects of Nd3+ on the microstructure, dielectric, and piezoelectric properties of the ceramics were studied. X-ray diffraction study reveals that Nd3+ ions diffuse into Ba(0.85-x)NdxCa0.15Zr0.1Ti0.9O3 lattice to form a solid solution of single perovskite structure having tetragonal symmetry. It was found that cell volume, crystallite size, tetragonality, d33 and Pr change with increasing Nd3+ content. d33 was optimized at 270pC/N for x = 0.015. The study reveals that optimum doping of Nd3+ in Ba(0.85-x)NdxCa0.15Zr0.1Ti0.9O3 can enhance its dielectric and piezoelectric properties.
