Abstract

The Leibfried-Schlömann (LS) equation, a commonly assumed model for the pressure dependence of thermal conductivity Λ, is tested by measurements on compressed H2O using a combination of the time-domain thermoreflectance method with the diamond anvil cell technique. The thermal conductivity of ice VII increases by an order of magnitude between 2 and 22 GPa, reaching Λ25 W m-1 K-1. Over a large compression range of 4%-33%, the LS equation describes the pressure dependence of Λ of ice VII to better than 20%.
