Abstract
A detailed study on the structural and dielectric characterization of the Nd doped SrTiO3 ceramics at radio frequencies were conducted in this paper. Sr1-xNdxTiO3 (x from 0 to 0.13) ceramics were synthesized using the conventional solid state ceramic route and the phase purity was confirmed through XRD analysis. XRD patterns of the ceramics showed almost similar peaks with no additional phases. A reduction in the lattice parameter can be observed with increase in the Nd content, which can be attributed to the possible lattice shrinkage due to the substitution by a smaller sized ion. The SEM images also showed a reduction in grain size which can be due the fact that Nd doping induces Sr and Ti vacancies in the system which inhibits the grain growth. The dielectric characterization at 1 MHz was done and optimal values of εr=5496 and tanδ=0.0925 were observed at x=0.1. Thus the synthesized ceramics can be used for energy storage applications.
