How to Measure the Thermal Conductivity for Insulation, …

WebFor n-docosane in the solid state, the thermal conductivity is determined to be 0.49 W m−1 K−1. A particle size of 200 μm with a spherical shape turns out to be optimal to increase the thermal conductivity. This allows the thermal conductivity of a compound with 10% graphite to increase by a factor of three compared to the pure paraffin.
