Perovskite textured La 2 Zr 2 O 7 (LZO) films were deposited on Ni tapes using sol-gel
process for fabrication of second generation high-T c superconductors. LZO solutions were
derived from acetate and alkoxide precursors. The effects of precursors, solvents, chelating
agents, and annealing conditions (temperature and time), on epitaxial growth of LZO were
investigated by XRD, SEM, EDS, and X-ray pole figure analysis. It was found that texture of
LZO depended on, solution preparation, and annealing conditions. Textured, homogenous …
