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.
