Abstract
Section titled āAbstractāIn this paper, a new method for in situ thermal conductivity measurements were established in diamond anvil cells (DAC) and achieve measurements at high pressure and high temperature under steady heat flow conditions. In this method, the traditional heat flux calibration was replaced by temperature measurement of anvils and finite element analysis. Furthermore, a DAC set-up with two heating furnaces was developed to better serve the proposed method. The thermal conductivity of four diamond anvils with different nitrogen content was measured and compared to reference to verify the methodās feasibility and serve as calibration for future measurements.
