Enthalpy - Improved Dielectric Insulation for Superconducting Wires.

Abstract

The purpose of this study was to investigate for the first time dielectric materials for enthalpy stabilization, the broad picture being that these materials would also serve as the dielectric-insulation coating. These new, inorganic materials resulted from basic research by the author into the specific heats of ferroelectric-type materials at low and glass which leads to enhanced specific-heat properties in several cases. In a particularly noteworthy case (60% SC-1C ceramic + 40% 7570 glass), the composite has a much larger specific heat (approx. = 0.07 J/cu cm/K) than the bulk ceramic alone below 7 K. There is evidence that the low thermal conductivities of all the composites are due to Kapitza resistance, and suggestions are made for improving these conductivities.
