This work presents a novel approach for preparation the oxygen deficient LaBaCaCu3Oy compound (La1113): temperature and duration optimization when applying the nitrate decomposition method. The XRD results reveal the presence of triple perovskite structure LaBaCaCu3Oy as a dominant phase crystallizing in the tetragonal system of the space group P4/mmm (a = 3.873(7) A°; c = 11.595(4) A°. The SEM observation shows a low porosity while EDAX data indicates the presence of the basic elements (La, Ba, Ca, Cu and O). The compound superconducting character is confirmed by AC susceptibility measurements with Tc = 63K.

Keywords: Optimization of nitrates decomposition method, X-Ray diffraction (XRD), Energy Dispersive Analysis of X-rays (EDS or EDAX), Superconductors.
