中文摘要	Bi/sub 2/Sr/sub 2/Ca/sub 1/Cu/sub 2/O/sub x / (Bi-2212) thick films on Ag wires were prepared by using the dip-coating method. It was found that the partial melting temperature and solid phase sintering temperature parameters during heat treatment strongly influence the phase formation of Bi-2212. The critical current density of dip-coated thin wire with a diameter of 0.5 mm can reach 10000 A/cm/sup 2/ at liquid nitrogen temperature and at 0 T magnetic field. Post-annealing treatments at different temperatures and oxygen partial pressures were executed in order to study the variation of critical temperature (T/sub c/) values. Results show that the optimal post-annealing temperature is 760 degrees C, and the corresponding T /sub c/ value is 96.98 K. During the post-annealing process, the higher the oxygen partial pressure is, the higher the T/sub c/ value will be. Furthermore, the properties of Bi-2212 materials have time effects when exposed to air, causing their critical temperature to change.
