High-pressure structural studies of eskolaite by means of single-crystal X-ray diffraction
The structural behavior of Cr2O3 was investigated up to ~70 GPa using single-crystal X-ray diffraction under a quasi-hydrostatic pressure (neon pressure medium) at room temperature. The crystal structure remains rhombohedral with the space group R3c (No. 167) and upon compression the oxygen atoms approach an ideal hexagonal close-packing arrangement. An isothermal bulk modulus of Cr2O3 and its ...
متن کاملDisorder in BaThF6 - anharmonic displacement parameters from high-pressure single-crystal x-ray diffraction data
Me(II)Me(IV)F6 ternary fluorides have a large potential for technological applications. In particular, BaThF6 is a promising scintillator material when doped with Ce [1]. In view of the limited knowledge about the crystal structure and stability of the compound, we decided to carry out a detailed structural study as a function of both temperature and pressure [2]. At ambient conditions, the com...
متن کاملHigh-pressure X-ray Diffraction Study of Diaspore
Effects of pressure on lattice parameters and molar volume of diaspore were studied to 25.5 GPa at 300 K by polycrystailine X-ray diffraction techniques. The pressure-volume data fit with a second-order Birch-Murnaghan equation of state give a bulk modulus K0 = 167.5 GPa. The bulk modulus is twice the previously reported, but unsubstantiated, value of K0 = 85 GPa by Ruoff and Vanderborgh [Phys....
متن کاملHigh pressure X-ray diffraction study of potassium azide
Crystal structure and compressibility of potassium azide was investigated by in-situ synchrotron powder X-ray diffraction in a diamond anvil cell at room temperature up to 37.7 GPa. In the bodycentered tetragonal (bct) phase, an anisotropic compressibility was observed with greater compressibility in the direction perpendicular to the plane containing N3 ions than directions within that plane. ...
متن کاملHigh-pressure X-ray diffraction study on α-PbF2
The high-pressure behaviour of α-PbF2 has been investigated by angular-dispersive synchrotron X-ray powder diffraction up to 6.55(8) GPa. The fit of a 3-order BirchMurnaghan equation-of-state gave the volume at zero pressure V0=194.14(4) Å 3 and the bulk modulus b0=47.0(6) GPa with the pressure derivative b’=7.9(4). The continuous-symmetry-measure approach has been used for the quantification o...
