英文摘要	By using diamond anvil cell (DAC), high-pressure Raman spectroscopic studies of orthophosphates Ba-3(PO4)(2) and Sr-3(PO4)(2) were carried out up to 30.7 and 30.1 GPa, respectively. No pressure-induced phase transition was found in the studies. A methanol:ethanol:water (16:3:1) mixture was used as pressure medium in DAC, which is expected to exhibit nearly hydrostatic behavior up to about 14.4 GPa at room temperature. The behaviors of the phosphate modes in Ba-3(PO4)(2) and Sr-3(PO4)(2) below 14.4 GPa were quantitatively analyzed. The Raman shift of all modes increased linearly and continuously with pressure in Ba-3(PO4)(2) and Sr-3(PO4)(2). The pressure coefficients of the phosphate modes in Ba3(PO4)2 range from 2.8179 to 3.4186 cm(-1) GPa(-1) for v(3), 2.9609 cm(-1) GPa(-1) for v(1), from 0.9855 to 1.8085 cm(-1) GPa(-1) for v(4), and 1.4330 cm(-1) GPa(-1) for v(2), and the pressure coefficients of the phosphate modes in Sr-3(PO4)(2) range from 3.4247 to 4.3765 cm(-1) GPa(-1) for v(3), 3.7808 cm(-1) GPa(-1) for v(1), from 1.1005 to 1.9244 cm(-1) GPa(-1) for v(4), and 1.5647 cm(-1) GPa(-1) for v(2).
