ABSTRACT: One of the basic ingredients in conventional preparation of cuprates-based superconducting materials such as the Nd-Ba-Cu-O superconducting system, especially the Nd1Ba2Cu3O7-δ phase is Barium Carbonate (BaCO3). It has the potential to produce the carbon dioxide (CO2) air pollutant. Therefore it is necessary to look for other materials as the source of Ba atom which does not produce CO2 gas. In this research has been successfully made the Nd1Ba2Cu3O7-δ phase with the Barium Hydroxide Octahydrate (Ba(OH)2·8H2O) as a source of Ba atom. The results of the characterization XRD has been shown the main peaks of the Nd1Ba2Cu3O7-δ phase. Refinement of the XRD data by using Rietica software, obtained the value of GofF (Goodness of Fit) = 1.7023 and lattice parameter a ≈ b
