Abstract :Thick Films of Bi2Sr2Ca2Cu3Ox were obtained on cleaved MgO insert ignore into journalissuearticles values(100); substrates from a component gel of stoichiometric composition with partial Pb substitution of Bi. Formation employeed screen printing method. Films were subjected two step annealing at temperatures above 850oC and 880\oC for the formation of the crystal structure and to attain superconducting properties. X-ray diffraction patterns and R-T measurements showed coexistence of the insert ignore into journalissuearticles values(2212); and insert ignore into journalissuearticles values(2223); phases for most of the films. Metallic behaviour in resistance and 110 K onset temperature were observed for good quality films with a completed superconducting transition between 78-103 K. Critical current densities were found in the range 3-5 A/cm2 at 80 K from current-voltage measurements.
