The thermal and electrical conductivities of natural diamond and of diamond films were measured between room temperature and 1000 C. Natural type IIa diamond, which is the purest diamond, was found to have a room temperature thermal conductivity of 24-25 W/cm-K which drops to 4-5 W/cm-K at 1000 C. Two diamond films (2mm thick) grown by microwave plasma CVD at Crystallume and Raytheon, were found to have thermal conductivities that fell exactly on the curve for the natural type IIa diamond.
