Abstract

Bi₂Sr₂CaCu₂O_x (2212) and (Bi,Pb)₂Sr₂Ca₂Cu₃O_x (2223) superconductors have orthorhombic crystal structures. They form platelike grains that at high temperatures grow primarily in the a-b planes and not in the c direction. The diffusional properties of Bi-Sr-Ca-Cu-O superconductors are so anisotropic that 2212 and 2223 cannot, in general, be densified by solid-state sintering. Densification can be improved by application of pressure or by use of transient liquid phases. Most of the useful bulk Bi-Sr-Ca-Cu-O superconductors are composites that contain metallic Ag, generally as a sheath or substrate. The Ag lowers the melting points of the superconductors, which has significant effects on microstructural development. The results of disparate sintering studies are presented and discussed.
