Dense Bi{sub 2}Sr{sub 1.7}CaCu{sub 2}O{sub x} (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 (J{sub c}) values were very low for all specimens. Dislocations, planar faults, and intergrowths of the Bi{sub 2}Sr{sub 2}CuO{sub x} phase, which were produced during the pressing, caused the intragranular J{sub c} to increase substantially. 10 refs.
