Severe implications by lead usage in microelectronic industry to the environment forced the findings of lead-free ceramics alternatives in recent years. Barium Titanate (BaTi0₃) based ceramics are particularly interesting among the various lead-free ceramics due to its high permittivity, low dielectric loss and exhibit piezoelectric effect. In this study, Neodymium (Nd)-doped BaTiOJ with composition ofBa1-xNdxTi03 at range (0 ~ x ~ 0.13) were prepared via conventional solid state method at high temperature. X-ray diffraction analysis shows that for Nd-doped BaTiOJ, the phase purity was obtained at final heating temperature of 1400 oc for 12 hours. Single phase ofNd-doped Ba TiDJ was observed from 0 ~ x ~ 0.1 0, however, the tetragonal distortion in undoped BaTi0₃ decreased with increasing x. The samples remain tetragonal until x ~ 0.015 and were cubic for 0 . 03 ~ x ~ 0.1 and appear to coalesce at x = 0.13. Maximum permittivity shifted to lower Curie temperature (Tc) from 120 octo 90 oc by doping at tetragonal region and remain linear without maximum at cubic region. For electrical properties, the sample ofx=0.005 exhibit a very high permittivity at room temperature which is 2586, lowest dielectric loss of 0.03, high piezoelectric charge constant about 55 pC.N-1 and high piezoelectric voltage constant about 0. 7 V m.N-1. The novelties in this study was the piezoelectric study was determined at doping concentration of 0 ~ x ~0 . 015 , whereby the piezoelectric properties increased with increasing poling voltage.
