Abstract
The equation of state of potassium metal at ∼25°C was measured to 6.1 GPa using energy-dispersive synchrotron radiation diffraction and a Drickamer-type cell. Previous piston-cylinder, shock wave and x-ray measurements disagree and this study is intended to help resolve these disagreements. Our P-V data fit closely to a Murnaghan equation of state and least-squares refinement gives Bo = 3.35 GPa and Bo′ = 3.28 in good agreement with recent theoretical calculations based on accurate experimental results.Keywords
