AbstractSolids that are liable to undergo physico-chemical changes are not well suited to the steady-state methods of thermal conductivity measurements. Two variable-state methods have been developed which both offer the advantage of producing neglibible thermal disturbance in the solid during the measurements. The first is a curve-fitting method with which all thermal properties of the test specimen can be determined from a test of less than 10-min duration. The second is a single-point method, especially suited for use at elevated temperatures and for study of the effect of moisture content or sluggish reactions on the thermal diffusivity.
