Abstract

High-Tc phase (2-2-2-3) samples of Pb,Sb-doped BiSrCaCuO superconductors were fabricated by a sinter-forge technique. Calcined powders as well as pre-sintered pellets were sinter forged at 861°C in flowing oxygen with an initial pressure of 4.5 MPa for 3.5 h and subsequently annealed. Best sinter-forged samples exhibited a majority of 2-2-2-3 phase, highly-oriented plate-like grains, and high bulk density values. The effects of processing conditions on microstructures and the electrical properties were investigated.
