Thermal conductivity could be calculated from thermal diffusivity measured with our system Thermowave Analyzer and heat capacity and density from literature values.

Thermal diffusivity or conductivity could be used to analyze the thermal resistance of materials and devices. It plays an important role for thermal designing.
