What is the thermal conductivity of KF? 

The thermal conductivity of KF has been studied in several papers. Experimental measurements using the steady-state variable gap technique were performed on eutectic LiF-NaF-KF, which showed a weak negative deviation of thermal conductivity with temperature . Molecular dynamics simulations using the Green-Kubo method predicted the thermal conductivities of molten alkali fluorides, including KF, and their mixtures. These simulations found that the thermal conductivity follows a scaling law for most systems, but a significant departure from the scaling law was observed in LiF-KF and LiF-NaF-KF mixtures . Another study used the plane heat-wave technique to measure the thermal conductivity of KF at ambient temperatures and pressures up to 3.8 GPa, finding that the effect of optic phonons in KF is negligible . However, the specific conductivity of the KF-K2TaF7 system was found to decrease with the addition of K2TaF7 .
