Richards, K T; Benfer, R H

Hot isostatic pressing (HIP) was studied as a method for processing bulk superconductors. Superconducting powder was derived from the calcination of nitrated Y2O3, CuO and BaCO3 powder. The powder was HIPed using pressures of 70, 140, and 210 MPa with temperatures of 820 deg C and 950 deg C for a hold time of 1 hour. The density, hardness and Young's modulus of HIPed samples were higher than those of sintered control samples. Superconducting transition temperatures 92 deg K were achieved without post-HIP annealing of the samples.
