Phase Transformations and Melting in KH2PO4to 40 kbar

摘要

The phase diagram of KH2PO4was determined to 40 kbar by differential thermal analysis. New phase transitions were found, and the diagram consists of six solid phases and the liquid. Dehydration of KH2PO4above 200deg;C is suppressed by pressure, and the melting curve was successfully determined to the highest pressure.
