The effective thermal conductivity of several powders of reasonably uniform particle size, and one powder of graded particle size, was measured in the temperature range of 100 °C to 1000 °C. Most of the results can be very satisfactorily explained by assuming that the effective conductivity of the powder is composed of two parts, the first part being a two-phase gas–solid conductivity, and the second an equivalent radiation conductivity.
