Chapter 1.7: Thermal Properties of Bi-2223 Wires
We introduced the thermal conductivity κ(T) of Bi-2223 wires sheathed with Ag-based alloys. The thermal conductivity of several sheathed Ag-based alloys was also summarized. For several kinds of DI-BSCCO tapes, κ(T) was reported and the anisotropic thermal conductivities of the stacked or sandwiched DI-BSCCO bundles were measured and analyzed using the heat flow model. The κ(T) data are useful and valuable for calculating the heat intrusion and thermal stability for the application to the superconducting coils and power current leads.
