| 摘 要： | 自发现Y—Ba—Cu—O超导体以来,又发现了零电阻温度为110K的Bi—Sr—Ca—Cu—O系(简称BSCCO,以下同)超导体材料和零电阻温度为120K的Tl—Ba—Ca—Cu—O系超导材料,其中BSCCO系超导材料因不含有毒元素及稀土元素而更受人注意。但是这类材料有几个致命的弱点,其中之一是高温相极不稳定,这种高温相既难形成,又很容易转变为低温相,因此较难获得具有单一高温相组成的BSCCO体材料;其次是BSCCO系体材

| Abstract: | The effect of composition, molding method and sintering process on the density of Bi-Sr-Ca-Cu-O superconducting bulk materials is studied. The experimental results show that 107K Bi-Sr-Ca-Cu-O superconducting ceramics of density as high as 6.10 g/cm~2 can be made by using high Pb content composition, small amounts of Sb~(5+) or W~(6+) aad a sintering-hot pressing-annealing process. |
