英文摘要	The pressure-induced phase transitions of PbCO3 are studied using synchrotron radiation in a diamond anvil cell at room temperature. The XRD measurement indicates that PbCO3 with an initial phase of aragonite-type structure undergoes two phase transitions at similar to 7.8 GPa and similar to 15.7 GPa, respectively. The higher-pressure phase appearing at similar to 15.7 GPa is stable up to 51.8 GPa. The two phase transitions are further confirmed by Raman scattering up to 23.3 GPa. During the decompression process, the high-pressure phases of PbCO3 are gradually recovered to the starting aragonite-type structure, but exhibit some hysteresis. The bulk modulus B-0 of the aragonite-type structure is obtained to be 63 +/-(3) GPa by fitting the volume-pressure data to the Birch-Murnaghan equation of states with B'(0) fixed to 4.
