摘要： A novel process of the production and processing of high quality, high T.sub.c (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 introducing the reacted mixture having a dominant amount of the tetragonal BSCCO phase into a metal sheath, and sealing the reacted mixture within said sheath, heating the mixture at a second selected processing temperature in an inert atmosphere with a second selected oxygen partial pressure for a second selected time period, the second processing temperature and the second oxygen partial pressure being cooperatively selected to form a dominant amount of an orthorhombic BSCCO phase in the reacted mixture. The sealed sheath is deformed to form an elongated precursor article of a desired texture; and thereafter heated at a third selected processing temperature in an inert atmosphere with a third selected oxygen partial pressure for a third selected time period. The third processing temperature and third oxygen partial pressure are cooperatively selected to convert at least a portion of the orthorhombic BSCCO phase to the final superconducting BSCCO material.

摘要： A method is described to prepare a highly textured oxide superconductor article in a single deformation-sinter process. A precursor article including a plurality of filaments comprising a precursor oxide having a dominant amount of a tetragonal BSCCO 2212 phase and a constraining member substantially surrounding each of the filaments is provided. Each of the filaments extends along the length of the article. The oxide article is subjected to a heat treatment at an oxygen partial pressure and temperature selected to convert a tetragonal BSCCO 2212 oxide into an orthorhombic BSCCO 2212 oxide and, thereafter, roll worked in a high reduction draft in a range of about 40% to 95% in thickness so that the filaments have a constraining dimension is substantially equivalent to a longest dimension of the oxide superconductor grains. The rolled article is sintered to obtain a BSCCO 2223 oxide superconductor.

摘要： A novel process of the production and processing of high quality, high T.sub.c BSCCO or (Bi,Pb)SCCO superconductors starts with fabrication of a forming a bundle including a plurality of billets, each billet containing at least one filament comprising a dominant amount of an tetragonal BSCCO phase with selected intermediate phases, and substantially surrounded by a constraining metal. The bundle is thermomechanically consolidated to form a multifilamentary precursor article by applying pressure and heat to the bundle under conditions cooperatively selected to cause interdiffusion of said constraining metal at the interfaces between said metal and said filaments and substantially complete elimination of voids in said bundle, and the consolidation step is completed before any high strain longitudinal deformation is performed on the bundle. The precursor article is then heated at a second selected processing temperature in an inert atmosphere with a second selected oxygen partial pressure for a second selected time period, the second processing temperature, the second time period and the second oxygen partial pressure being cooperatively selected to form a dominant amount of an orthorhombic BSCCO phase in the reacted mixture. It may then be deformed to form an elongated precursor article of a desired texture; and thereafter heated at a third selected processing temperature in an inert atmosphere with a third selected oxygen partial pressure for a third selected time period, all cooperatively selected to convert at least a portion of the orthorhombic BSCCO phase to the final superconducting BSCCO material.

摘要： 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.

摘要： A multicomponent powder useful in the formation of BSCCO-2223 is provided comprised of orthorhombic BSCCO-2212 and alkaline earth cuprate, without formation of undesirable secondary phases such as alkaline earth bismuthates and alkaline earth plumbates. A method for the production of the multicomponent powder includes providing a mixture of raw materials comprising constituent metallic elements in a ratio corresponding to a superconducting BSCCO-2223 material and heating the mixture under conditions which form a dominant amount of the orthorhombic BSCCO phase and the alkaline earth cuprate phase while preventing formation of an undesirable secondary phase selected from the group of alkaline earth plumbates and alkaline earth bismuthates. A subsequent heating step converts the multicomponent powder into the BSCCO-2223 and subsequent deformation and annealing processes may be used to form a substantially single phase, highly textured (Bi,Pb)SCCO-2223 superconductor article.
