Effect of substitution of neodymiumon electrical and dielectric properties of barium titanate (BT) ceramics

Sukhleen Bindra Narang, Anantvir Singh, Kunal Pubby

Ceramic samples of a complex structural formula Ba2-xRe4+2x/3Ti18O54 where Re=Nd(Neodymium) and x=0.0 & x=0.2 were prepared by a high temperature solid state reaction technique. The dielectric properties (åÂ’, tanäand AC Conductivity) were measured on network analyser in the frequency range of 20Hz - 1 MHz at room temperature. The dielectric properties of samples were found out to be a function of weight percentage of rare earth elements used and frequency of applied electric field. Dielectric conductivity was derived from the conductance and geometrical dimension of the samples in the same frequency range. The capacitance values were obtained directly from the network analyser.
