| 英文摘要 | The structural stability and elastic properties of celestine have been investigated at room temperature and pressure up to 15gpa, by using in situ angle-dispersive x-ray diffraction and a diamond anvil cell. no phase change is observed within the range of pressure in this study. analysis of room temperature p-v data to a third-order birch-murnaghan (bm) eos yields: the zero-pressure volume v-0 = 306.0(6) angstrom(3), isothermal bulk modulus k-0 = 62(5) gpa and its pressure derivative k'(0) = 11(1). if k'(0) is fixed at 4, then the isothermal bulk modulus is k-0 = 98(2) gpa. in addition, the axial compressiblity moduli of the three unit cell axes of celestine are obtained as k-a0 = 102(2) gpa, k-b0 = 92(2) gpa and k-c0 = 98(2) gpa, indicating the anisotropy of axial compressibility, with the a axis the most incompressible and the b axis the most compressible. furthermore, the elastic properties of barite-type sulfates are discussed by combining the results in this study with previous studies on barite-group minerals. |
