Morphological and Structural Analysis of Nd1(Fe)0.2Ba1.8Cu3O7-δ Oxide Material

Abstract

Nd1(Fe)0.2Ba1.8Cu3O7-δ oxide material have been successfully synthesized by solid-state reaction with modified heat treatment process to improve the heat time efficiency, calcination at 950°C for six hours, sintering at 975°C fo six hours, and annealing at 450°C for six hours, respectively. The X-ray diffraction pattern shows that a single-phase form of Nd1(Fe)0.2Ba1.8Cu3O7-δ is an orthorhombic (Pmmm) structure. The Rietveld refinement analysis found, the lattice parameter are a = 3.8758Å, b = 3.9101Å, and c = 11.7190Å with χ2 = 1.394%. The SEM-EDAX image shows that the samples are form clusters with size estimates of 10 - 40μm, and the elemental composition of the oxide materials is Ba rich.
