Abstract

In synthesizing La_2-xSr_xCuO₄ ceramic superconductors through the solid state reaction of precursor powders, failure to account for hydration of La₂O₃ to La(OH)₃ produced an overall La³⁺ ion deficiency. This deficiency resulted in the formation of a significant amount of a second phase, which was determined by X-ray diffraction to be an oxygen deficient perovskite of the type La_2-xSr_xCu₂O₅.
