We have developed a near-net-shape process for Ag-clad Bi-2212 superconductors. This alternative to the powder-in-tube process offers the advantages of nearly continuous processing, minimization of processing steps, reasonable ability to control the

Several perovskite-type oxides (ABO3) containing transition metals on the B-site show mixed (electronic/ionic) conductivity. These mixed-conductivity oxides are promising materials for oxygen-permeating membranes that can operate without electrodes o

Three phase assemblages were used to produce Bi2Sr2CaCu2Ox (2212) during sintering: a mixture of 20% Ca-rich 2212+80%2212, partially synthesized 2212, and Bi2Sr2CuOx (2201)+(1/2 Ca2 CuO3+1/2 CuO) (denoted 0011). The mixture of 2201+0011 produced high
