Barium Hydroxide Octahydrate (Ba(OH)2 8H2O) as a Substitute Alternative for Barium Carbonate (BaCO3) in Synthesis Superconductor of Nd1Ba2Cu3O7-d Phase

One of the basic ingredients in conventional preparation of cuprates-based supercon-ducting materials such as the Nd-Ba-Cu-O superconducting system, especially the Nd1Ba2Cu3O7-? 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 mate-rials as the source of Ba atom which does not produce CO2 gas. In this research has been successfully made the Nd1Ba2Cu3O7-? phase with the Barium Hydroxide Octahy-drate (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-? 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
