Due to the toxicity of lead, there is an urgent necessity to develop lead-free alternatives to replace the currently dominant lead-based piezoelectric such as Pb(Zr,Ti)O3 (PZT). Na0.5K0.5NbO3 based piezoelectric nanomaterial are promising because of their relatively high Curie temperatures as well as good piezoelectric coefficients among the non-lead piezoelectrics. We have successfully synthesized 3-dimensional perovskite nanocubes of functional ternary transition-metal oxide of sodium potassium niobate Na0.5K0.5NbO3 by using novel synthesis method. We have carried out resistance and impedance spectroscopy studies at low temperature using two probe technique. For this electrical measurement, we have used CCR system. There has been much interest in the texturing of electro ceramics, due to the possibility of achieving enhanced electrical properties. A major purpose for this electrical characterization study is to examine how Na0.5K0.5NbO3 (NKN) pellet behaves under low temperature. Copyright © 2017 VBRI Press.
