摘要：

Hot isostatic pressing (HIPing) with an oxygen donor 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 69, 138, and 207 MPa at 820-degrees-C. BaO2 was used as an oxygen donor during HIPing. The density, hardness, and Young's modulus of HIPed samples were higher than those of sintered control samples. Superconducting transition temperatures > 92 K were achieved without post-HIP annealing of the samples in oxygen.
