Abstract
The temperature dependence of the thermal conductivity of indium has been measured in the high-temperature regime for both solid and liquid phases to an accuracy of +or-1%. These data lead to a Wiedemann-Franz ratio that is (i) temperature independent for the solid, (ii) temperature independent for the liquid, and (iii) continuous across the melting point. The value of the measured Wiedemann-Franz ratio is 9% higher than the theoretical Lorenz number.Keywords
