Precise Measurement of Thermal Conductivity at High Temperatures (100–1200 K)

Abstract

Various absolute steady-state methods of measuring thermal conductivity can be made to yield, verifiably, experimental results accurate to within ± 2% from 100 to 1200 K, and for conductivity values from 0.1 to 5 W/cmK. This statement is substantiated by a detailed analysis of the results obtained by eight different systems in three laboratories on ten metals: Cu, Ag, Au, Pd, Pt, W, Cr, Armco Iron, and the alloys Nb-10 W and Inconel 702. The experimental systems by which these results were obtained are also briefly described.
