title = "Sintering of bulk high-Tc superconductors: Bi-Sr-Ca-Cu-O",
abstract = "Bi2Sr2CaCu2Ox (2212) and (Bi,Pb)2Sr2Ca2Cu3Ox (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.",
