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: Raw material powder for a bismuth oxide superconductor is molded with addition of an organic vehicle, and the molded raw material is heat treated for removing the organic vehicle before the molded raw material is metal-coated. In this heat treatment, conditions not more than those expressed as T = -71.5 x log H + 600 are applied as to relation between temperature (T) [unit: DEG C] and time (H) [unit: hour]. Thus, phase transformation of 2212 phases mainly composing the raw material is suppressed so that a large amount of 2223 phases having a relatively high critical temperature are formed when heat treatment is performed after metal coating.

Abstract: An oxide ceramic superconductor is obtained by mixing the oxides of bismuth, strontium, calcium and copper, the atomic ratios of the metals corresponding to those of a high-temperature superconductor. A powdered alkaline earth indate of formula (Sr,Ca)In2O4 is added to the mixture, which then undergoes prolonged heating in the presence of oxygen. The presence of the indate promotes the formation of a phase with a transition temperature of 110 K.

Abstract: A high temperature treatment process whereby superconducting phases and materials can be obtained based on a treatment by high temperature of a non-superconducting phase of a cupric oxide compound. The high temperature processing provides an alternate synthetic route in the search for a new high Tc superconductors and a new high Tc copper oxide material is formed with non-rare earth elements Bi-Sr-Cu-O. Similarly a nominal composition YSrCuO4-y is high temperature processed to exhibit superconducting transitions at temperatures previously unattainable with low temperature heat treatment methods.

Abstract: A method of making an oxide superconductor article includes subjecting an oxide superconductor precursor to a texturing operation to orient grains of the oxide superconductor precursor to obtain a highly textured precursor; and converting the textured oxide superconducting precursor into an oxide superconductor, while simultaneously applying a force to the precursor which at least matches the expansion force experienced by the precursor during phase conversion to the oxide superconductor. The density and the degree of texture of the oxide superconductor precursor are retained during phase conversion. The constraining force may be applied isostatically.

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 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.

Abstract: In order to obtain a ceramic-type superconductive wire, a bulky ceramic-type superconductor or a precursor thereof that is pretreated such that the crystalline structure is oriented is charged into a metallic pipe, subjected to the working for decreasing the diameter so as to be elongated, and is heat-treated. In the thus obtained superconductive wire, the bulk consisting of the superconductor or the precursor thereof maintains the crystalline orientation. Namely, there is obtained a superconductive wire having a high critical current density. In order to further increase the critical current density, it is desirable to repeat the step for decreasing the diameter and the step of heat treatment alternatingly plural times.
