Abstract

Ba(Nd<subscript>x</subscript>Ti<subscript>(1-2x)</subscript>Nb<subscript>x</subscript>)O<subscript>3</subscript> (x=0.025, 0.05, 0.1 & 0.2) and (Na<subscript>0.5</subscript>Bi<subscript>0.5</subscript>)(Nd<subscript>y</subscript>Ti<subscript>(1-2y)</subscript> Nby)O<subscript>3</subscript> (y=0.0125, 0.025 & 0.05) ceramics were prepared through solid state sintering route. In the present paper X-ray diffraction (XRD) data was obtained using (Philips X-pert Pro Pan Analytical: Model PW3040/60). The XRD data was simulated using modified Arrhenius and Lorentz equation using ORIGIN 6.1 software which was proposed by us earlier. In the case of Ba(Nd<subscript>x</subscript>Ti<subscript>(1-2x)</subscript>Nb<subscript>x</subscript>)O<subscript>3</subscript> ceramics the values of lattice parameter obtained using modified Arrhenius and Lorentz equations are 3.9597Ao, 4.2534Ao, 5.2364Ao & 5.2690Ao for x=0.025, 0.05, 0.1 & 0.2 respectively. The average values of activation energy for x-ray scattering are 74.47 meV, 85.21 meV, 90.20 meV & 95.79 meV for x=0.025, 0.05, 0.1 & 0.2 respectively. Similar simulation studies were also carried on (Na<subscript>0.5</subscript>Bi<subscript>0.5</subscript>)(Nd<subscript>y</subscript>Ti<subscript>(1-2y)</subscript>Nby)O<subscript>3</subscript> ceramics and the results are presented in this paper.
