The crystal structure of wolframite type tungstates at high pressure

Single-crystal structure determinations of wolframite-type struc­ tures were performed using a diamond anvil cell with beryllium gaskets. Unit cell parameters of MgW04, MnW04 and CdW04 were determined at several pressures up to 8.0 GPa and structure refinements were performed up to 6.0 GPa. The high pressure behaviour is compared with the behaviour of the related scheelite-type structure. All i...

Prediction of incommensurate crystal structure in Ca at high pressure.

Ca shows an interesting high-pressure phase transformation sequence, but, despite similar physical properties at high pressure and affinity in the electronic structure with its neighbors in the periodic table, no complex phase has been identified for Ca so far. We predict an incommensurate high-pressure phase of Ca from first principle calculations and describe a procedure of estimating incomme...

Compressibility and crystal structure of sillimanite, Al2SiO5, at high pressure

R.T. Downs Department of Geosciences, University of Arizona, Tucson, Arizona 85721, USA Abstract The unit-cell dimensions and crystal structure of sillimanite at various pressures up to 5.29 GPa have been refined from single-crystal X-ray diffraction data. As pressure increases, a and b decrease linearly, whereas c decreases nonlinearly with a slightly positive curvature. The axial compression ...

consequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
