Simulation of XRD data of Ba(NdxTi(1-2x)Nbx)O3 ceramics with cubic crystal structure and (Na0.5Bi0.5)(NdyTi(1-2y)Nby)O3 ceramics with rhombohedral crystal structure by modified Arrhenius and Lorentz equations

Abstract

Ba(NdxTi(1-2x)Nbx)O3 (x = 0.025, 0.05, 0.1 & 0.2) and (Na0.5Bi0.5)(NdyTi(1-2y)Nby)O3 (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(NdxTi(1-2x)Nbx)O3 ceramics the values of lattice parameter obtained using modified Arrhenius and Lorentz equations are 3.9597 Ao, 4.2534 Ao, 5.2364 Ao & 5.2690 Ao 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 (Na0.5Bi0.5)(NdyTi(1-2y)Nby)O3 ceramics and the results are presented in this paper.
