Abstract

Bi_2.1Sr_1.96Ca_xCu_2.0O_x (Bi-2212) thick films with Ag substrates were prepared through dip coating process. By X-ray diffraction (XRD) and scanning electron microscopy (SEM) characterizations, the influences of heat treatment parameters on the phase transition process and the aligned growth of Bi-2212 grains have been systematically studied. The maximum heat treatment temperature, T_max, and cooling rate, R_c has been optimized. Meanwhile, the influences of the coating density on the microstructures and the transport properties have also been discussed by applying an additional cold pressing. The J_c value of over 7300 A/cm² (77 K, self field) has been obtained from the direct powder pressing process, which is over 60% higher than that from the traditional dip coating thick film.
