Abstract
The thermal conductivity of beryllium oxide samples produced by isopressing at 20 ton in-2 and sintering at 1505°C was measured in the range 300ºK to 1200ºK. The BeO compacts measured had a density of 2.85 g cm-3 and an average grain size of 6μ. The thermal conductivity was found to be given by the relation:
k = 1.01 x 10 4 T-1.47, where k is the thermal conductivity (watt(cm degK)-1) and T is the absolute temperature. This result is compared with other thermal conductivity measurements on similar materials.
