Bi2Sr2CaCu2O8+delta (Bi-2212) superconducting thin films with c-axis epitaxial orientation were prepared on LaAlO3 (LAO) single crystal substrates via a Sol-Gel technique using metallic acetates as starting materials. The influence of the growth temperature and oxygen partial pressure (pO(2)) on the phase purity and superconducting properties of Bi-2212 was discussed. The results show that Bi-2212 films prepared at 820 degrees C with the pO(2) of 1.4 KPa exhibit good in-plane and out-of-plane growth textures and excellent superconducting properties with high critical transition temperature (T-c) of 88 K and narrow transition width (Delta T-c) of 4.8 K.
