Abstract

A new C14 Laves phase was synthesized by direct reaction of potassium and silver at high pressure in a diamond anvil cell. The structure was refined by Rietveld analysis on powder diffraction data in the space groupP63/mmcto anRF2value of 0.034. The lattice parameters area=5.589(5) andc=9.476(1). Formation of this phase under pressure is in agreement with predictions based on Miedema's rules. A novel double-sided laser heating system was developed for the synthesis of KAg2.
