Simulation of XRD data of Ba(Nd_xTi_(1-2x)Nb_x)O₃ ceramics with cubic crystal structure and (Na_0.5Bi_0.5)(Nd_yTi_(1-2y)Nb_y)O₃ ceramics with rhombohedral crystal structure by modified Arrhenius and Lorentz equations

Abstract

Ba(Nd_xTi_(1-2x)Nb_x)O₃ (x = 0.025, 0.05, 0.1 & 0.2) and (Na_0.5Bi_0.5)(Nd_yTi_(1-2y)Nb_y)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(Nd_xTi_(1-2x)Nb_x)O₃ ceramics the values of lattice parameter obtained using modified Arrhenius and Lorentz equations are 3.9597 A^o, 4.2534 A^o, 5.2364 A^o & 5.2690 A^o 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_0.5Bi_0.5)(Nd_yTi_(1-2y)Nb_y)O₃ ceramics and the results are presented in this paper.
