Abstract

Dense (Bi, Pb)₂Sr₂Ca₂Cu₃O_x bars were fabricated by sinter forging. The bars were highly phase-pure and exhibited strong textures in which the c axes of the platelike grains were preferentially aligned parallel to the pressing direction. Transport critical current densities increased with texture, reaching a maximum of 8*10³ A cm^-2 at 77 K in a self-field. Optimal processing in air occurred at 845-850 degrees C.
