Effect of Na substitution and Ag addition on the superconducting properties of Bi-2212 textured materials 2017 Access copy available to the general public Unrestricted The effect of Ag addition on the structural and superconducting properties of Bi2Sr2Ca0.925Na0.075Cu2Oy + x wt% Ag materials with x = 0, 1, 3, and 5 prepared by sol–gel method, followed by directional growth using the laser floating zone (LFZ) technique has been investigated. Powder XRD measurements demonstrate that all samples are composed by nearly single Bi-2212 phase. SEM micrographs and EDX results confirms that Bi-2212 is the major phase with minor amounts of a Bi-free one (Sr, Ca)CuO2 and metallic Ag. According to the magnetic results, Ag does not modify the superconducting critical temperature, Tc, but significantly increases the magnetic hysteresis loop area. The magnetic critical current density is maximum in the 3 wt% Ag containing samples, due to the larger grain clusters found in these samples, reaching 2.1 × 105 A/cm2 at 10 K. Moreover, Ag addition also improves the rods mechanical properties, determined by three point bending tests. The highest bending stress is also reached in the 3 wt% Ag samples. info:eu-repo/grantAgreement/ES/DGA/T12 info:eu-repo/grantAgreement/ES/MINECO-FEDER/ENE2014-52105-R info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2013-46505-C3-1-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.324 2017 ENGINEERING, ELECTRICAL & ELECTRONIC 100 / 260 = 0.385 2017 Q2 T2 PHYSICS, CONDENSED MATTER 32 / 67 = 0.478 2017 Q2 T2 PHYSICS, APPLIED 55 / 146 = 0.377 2017 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 118 / 283 = 0.417 2017 Q2 T2 0.503 2017 Atomic and Molecular Physics, and Optics 2017 Q2 Biomedical Engineering 2017 Q2 Electronic, Optical and Magnetic Materials 2017 Q2 Electrical and Electronic Engineering 2017 Q2 Condensed Matter Physics 2017 Q2 Biophysics 2017 Q3 Biomaterials 2017 Q3 Bioengineering 2017 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Nane, O.
