摘　　要：用硝酸盐共分解法得到的 T_c0 为92K 的 YBCO 超导粉料,制备了单面银基复合带材,实验结果表明,这种带材的 J_c（77K,0T）可达5300A/cm²,比同样工艺下的用固相反应法原粉制备的带材的 Jc 高4倍,而且,前者在水中具有较好的稳定性.Ag-YBCO composite, tapes have been prepared with Nitric salt codecompsition superconducting powders. It was found that the critical current density of this tapes is much higher than that of the tapes prepared with the conventional solid state reaction powders. Apart from the high Jc value of 5300 A/cm2 which is about 4 times larger than the later, the former also has a higher stability in water.
