High-pressure melting curves of alkali halides

Abstract
The melting curves of CsI, KCl, and KBr were measured in a diamond-anvil cell to temperatures of 3500 K and pressures up to 370 kbar. Theoretical calculations for CsI, made by directly integrating the Clapeyron equation, are in good agreement with the measurements and predict a crossing of the CsI and Xe melting curves near 410 kbar and 4280 K. © 1996 The American Physical Society.
