Abstract

An article and method of manufacture of (Bi,Pb)-Sr-Ca-Cu-O superconductor are disclosed. The superconductor is manufactured by preparing a first powdered mixture of bismuth oxide, lead oxide, strontium carbonate, calcium carbonate and copper oxide. A second powdered mixture is then prepared of strontium carbonate, calcium carbonate and copper oxide. The mixtures are calcined separately with the two mixtures then combined. The resulting combined mixture is then subjected to a powder in tube deformation and thermal processing to produce a substantially phase pure (Bi,Pb)-Sr-Ca-Cu-O superconductor. 5 figs.

Synthesis of Bi{sub 1.8}Pb{sub 0.4}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub x} superconductor

Patent Smith, M G

Two-powder processes for the synthesis of superconducting (Bi, Pb)-2223/Ag-clad wires by the oxide-powder-in-the-robe are provided. The first precursor powder, of nominal stoichiometry CaCuO{sub x}, is a solution-synthesized mixture of Ca{sub 0.45}Cu{sub 0.55}O{sub 2} and CaO. Using these oxide precursor mixtures, superconducting tapes with well-aligned grains and reproducible critical current densities J{sub c} in the range of 20,000 to 26,000 A/cm{sup 2} at 75 K in self-field after annealing less than 200 hours were obtained. 2 figs.
(Bi, Pb){sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub x} superconductor and method of making same utilizing sinter-forging

Patent Chen, N; Goretta, K C; Lanagan, M T

A (BiPb){sub 2}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub x}(Bi223) superconductor with high J{sub c}, phase purity, density and mechanical strength is formed from Bi2223 powder which is synthesized from a mixture of Bi{sub 2}O{sub 3}, PbO, SrCO{sub 3}, CaCo{sub 3} and CuO. The mixture is milled, then dried and calcined to synthesize the Bi2223 powder with the desired phase purity. The calcination is performed by heating the dried mixture for 50 hours at 840 C. The partially synthesized powder is then milled for 1--4 hours before calcining further for another 50 hours at 855 C to complete the synthesis. After calcination, themore »« less

Synthesis and microstructure of the 2223 phase (Bi{sub 2.0}Sr{sub 2.0}Ca{sub 2.0}Cu{sub 3.0}O{sub x}) in the (Bi,Pb)-Sr-Ca-Cu-O system obtained from freeze dried precursors

Book Krishnaraj, P; Lelovic, M; Deis, T A; ...

Amorphous precursor powders for Bi{sub 1.8}Pb{sub 0.4}Sr{sub 2}Ca{sub 2.2}Cu{sub 3}O{sub x} and Bi{sub 1.8}Pb{sub 0.4}Sr{sub 2}Ca{sub 2.0}Cu{sub 3}0{sub x} (2223) were prepared by a freeze-drying process incorporating a splat-freezing step. The critical parameters affecting the drying process are discussed. The freeze-dried powders have high reactivity and led to essentially phase pure 2223 phase formation in 12 hr. The microstructure of the 2223 shows fine coherent particles of 2201 in the matrix. The grain boundaries of the 2223 grains appear to be clean, leading to good intergrain contact between 2223 grains. It was shown that both lead content and oxygen partialmore »« less
