โฆ Synopsis
Measurements of the thermal conductivity of SX-5 graphite from -100ยฐC to 2500ยฐC are reported. The temperature range was covered by three techniques: a transient technique at the lower temperatures, a series-comparison method for the intermediate range, and a radial heat flow method for the high temperatures. The radial heat flow method, when used with anisotropic materials, requires a two-dimensional heat flow analysis of the data; the approach which was used in this work is described. At temperatures above 250ยฐC the conductivity appears to follow a l/T relation, which is characteristic of graphites in particular and of Umklapp thermal resistive processes in general.
