Title: High pressure and high temperature behaviour of ZnO

Abstract

The thermodynamic properties with the wurtzite (B4) and rocksalt (B1) phases of ZnO under high pressures and high temperatures have been investigated using Tait's Equation of state (EOS). The effects of pressures and temperatures on thermodynamic properties such as bulk modulus, thermal expansivity and thermal pressure are explored for both two structures. It is found that ZnO material gradually softens with increase of temperature while it hardens with the increment of the pressure. Our predicted results of thermodynamics properties for both the phases of ZnO are in overall agreement with the available data in the literature.

  • The new monoclinic cerium borogermanate Ce{sub 6}(BO{sub 4}){sub 2}Ge{sub 9}O{sub 22} was synthesized under high-pressure and high-temperature conditions in a Walker-type multianvil apparatus at 10.5GPa and 1200 deg. C. Ce{sub 6}(BO{sub 4}){sub 2}Ge{sub 9}O{sub 22} crystallizes with two formula units in the space group P2{sub 1}/n with lattice parameters a=877.0(2), b=1079.4(2), c=1079.1(2) pm, and {beta}=95.94(3){sup o}. As the parameter pressure favours the formation of compounds with cations possessing high coordination numbers, it was possible to produce simultaneously BO{sub 4}-tetrahedra and GeO{sub 6}-octahedra in one and the same borogermanate for the first time. Furthermore, the cerium atoms show high coordination numbersmore » (C.N.: 9 and 11), and one oxygen site bridges one boron and two germanium atoms (O{sup [3]}), which is observed here for the first time. Besides a structural discussion, temperature-dependent X-ray powder diffraction data are presented, demonstrating the metastable character of this high-pressure phase.« less
  • NaBi(MoO{sub 4}){sub 2} has been characterized by single-crystal and powder X-ray diffraction in the temperature and pressure ranges 13-297K and 0-25GPa, respectively. The domain structure developing below T{sub c}=241K proves that NaBi(MoO{sub 4}){sub 2} undergoes a ferroelastic phase transition associated with tetragonal I4{sub 1}/a to monoclinic I2/a symmetry change. The character of the unit cell evolution as a function of temperature indicates a continuous transition with the spontaneous strain as an order parameter. The structural distortion, due to small displacements of Bi{sup 3+} and Na{sup +} ions, develops slowly. Therefore the overall changes, as measured in single-crystal diffraction at 110more » and 13K, appear to be subtle. High-pressure powder X-ray diffraction shows that the elastic behaviour is anisotropic, the linear compressibility along the a- and c-axes of the tetragonal unit cell being {beta}{sub a}=2.75(10)x10{sup -3} and {beta}{sub c}=4.30(10)x10{sup -3}GPa{sup -1}, respectively. The cell contraction, stronger along the c-axis, causes the distances between the MoO{sub 4} layers to be shortened. Consequently, the cation migration in the channels formed by MoO{sub 4} tetrahedra becomes hindered, and any symmetry lowering phase transition is not observed up to 25GPa. The zero-pressure bulk modulus is B{sub 0}=76(5)GPa, and its pressure derivative B{sub 0}{sup '}=5.1(5)« less
  • The ASDEX Pressure Gauge is, at present, the main candidate for in-vessel neutral pressure measurement in ITER. Although the APG output is found to saturate at around 15 Pa, below the ITER requirement of 20 Pa. We show, here, that with small modifications of the gauge geometry and potentials settings we can achieve satisfactory behaviour up to 30 Pa at 6 T.
