Abstract

The compressibility of γ-K2CO3 within the pressure range of 0.001-23.3 kbar and room temperature was determined by in situ synchrotron powder diffraction measurements in diamond anvil cell. The modification of the diffraction pattern was fixed at P > 23.3 kbar. This modification can be explained by a reconstructive phase transition. The amorphization of the high pressure phase was fixed on decompression.
