Abstract
A method has been developed for determining thermal conductivity by measuring temperatures at the center of the faces of a rectangular rod which is heated electrically. Radiation of energy causes a difference in the temperatures of the short and long faces, and this difference is related to the thermal conductivity. The emissivity of the surface must be known. The method has been applied successfully by Dr. Ralph Muller, of the Los Alamos Scientific Laboratory, to the measurement of the thermal conductivity of graphite at temperatures near 2500°K, when other standard methods failed.
