    Abstract: A novel process of the production and processing of high quality, high Tc (Bi, Pb)SCCO superconductors starts with fabrication of a precursor article including selected intermediate phases with desired chemical and structural properties. The precursor fabrication includes mixing raw powders with a desired ratio of Bi:Pb:Sr:Ca:Cu elements and reacting the mixture under different selected reaction conditions that form a precursor powder with a dominant (Bi, Pb)SCCO 2212 phase and without Ca-Pb-O phase, wherein the 2212 phase may be the orthorhombic 2212 phase. The precursor article is then subjected to optimized reaction and mechanical deformation processes that lead to a reaction induced texturing and deformation induced texturing, respectively. A heating process is used to convert the precursor powder to the 2223 phase and subsequent deformation and annealing processes may be used to form a substantially single phase, highly textured (Bi, Pb)SCCO 2223 superconductor with high Jc.

    Abstract: The invention relates to methods of making a superconductor. A superconductor precursor layer (15) is deposited on a substrate (12) having optional intermediate or buffer layers (16, 18, 22) by a solution coating method and treated using relatively few temperature ramps, varying pressures of water vapor, and/or isothermal treatment steps. The methods and compositions can be used to form superconductor material intermediates preferably metal oxyfluoride intermediates of YBCO that have relatively few cracks and/or blisters.
