Abstract

Dense Bi2Sr1.7CaCu2Ox (2212) superconductor pellets were made by hot isostatic pressing in an inert atmosphere. The pellets exhibited a small amount of preferred orientation of the grains. The transport critical current density (Jc) values were very low for all specimens. Dislocations, planar faults, and intergrowths of the Bi2Sr2CuOx phase, which were produced during the pressing, caused the intragranular Jc to increase substantially.
