Abstract
The coefficient of thermal conductivity of any sample can be measured without any pre-processing to the sample by putting an electric heater and a thermo-electric couple between a block made of reference material whose coefficient of thermal conductivity is known and the sample, flowing electric current in said heater, measuring the temperature of said heater with said thermo-couple, and calculating the coefficient of thermal conductivity of the sample according to the measured data. The present inventors introduce herein a novel equation for that calculation.
