| 英文摘要 | The pressure-volume relations of a natural manganite [gamma-mnooh] were measured at ambient temperature and high pressures up to 12.7 gpa using a diamond anvil cell ( dac) equipment and synchrotron radiation x-ray diffraction technique. no phase transition has been observed within the whole pressure range in this study. analysis of pressure-volume data on p21/c setting structure to a third-order birch-murnaghan equation of state yielded: zero-pressure volume v0 = 135.46( 4) angstrom(3), isothermal bulk modulus k-0 = 86( 2) gpa and its pressure derivative k'(0) = 6.8( 6). the axial compression behavior shows that the manganite is a compression anisotropic mineral with k-ao = 93( 4) gpa, k-b0 = 62( 5) gpa, k-c0 = 82( 4) gpa, which reveals that the a-axis is the least compressible, then b-axis is the most compressible, and c-axis is between them. comparing the compressibility of manganite based on p2(1)/c with b2(1)/d setting showed that the different of crystallization orientation was the unique reason for the different axial modulus. furthermore, we also compared the compressional properties manganite with pyrolusite ( beta-mno2) and the hydroxides of inooh-related structure which were isotopological to manganite (b2(1)/d), and inferred that the combinations of jahn-teller effect and hydroxyl were the major reasons for the far less bulk modulus of manganite than that of the pyrolusite, and the jahn-teller effect and the least electronegativity central coordinated cation-mn3+ in manganite were the reasons for having the smallest bulk modulus of manganite among the inooh-related hydroxides. |
