“…For Bi-2212 tapes on a silver substrate [4] or in a silver sheath [5], partial melt processing can produce high c-axis alignment and consequently reduce weak links to a very great extent. However, in fully-processed samples there exist non-superconducting second-phase inclusions which seriously disrupt the effective current-carrying paths and degrade the critical current density.…”

“…Silver does not dissolve into the superconducting phases and, thus, does not cause any detrimental effects on the superconducting properties. 1 Silver dissolves into the oxide liquid and reduces the melting temperatures of the superconducting phases by ∼30 K during the partial-melt processing of 2 2 1 2 on silver. 2,3 This work is part of a project to evaluate the thermodynamic properties and phase relations in the Ag-Bi-Sr-Ca-Cu-O system, especially to quantify the influence of silver on the phase equilibria that are relevant for the processing of the 2 2 1 2 and 2 2 2 3 compounds.…”

“…The monotectic transformation temperature (T mono ) (i.e., the emergence of the oxide liquid) and the melting point of silver (T m,(Ag) ) are determined in these atmospheres. These experiments are described later in section II (1). The cationic compositions of the oxide liquid phases are determined via energy-dispersive X-ray spectroscopy (EDX) (see section II(2)).…”

“…[1][2][3] The powder-in-tube method ͑Ag sheath method͒ is also effective to obtain a grain oriented microstructure if the method is used together with the meltsolidification method. 4 The Bi-2212 shows very high upper critical field ͑or irreversibility field͒ at low temperatures, therefore, grain oriented Bi-2212/Ag tape conductors show very high J c values, Ͼ10 5 A/cm 2 even in magnetic fields above 25 T at ϳ4.2 K. 5 So the Bi-2212/Ag conductors are very promising for high magnetic field applications where no conventional metallic superconductors are available. 6 The microstructure and superconducting properties of the melt-solidified Bi-2212/Ag tapes are very sensitive to several parameters such as the maximum temperature of the heat treatment schedule, cooling rate from the partially molten state, the thickness of oxide layer, and the substrate material.…”
