Viscosity of liquid Fe at high pressure
Synchrotron x-ray radiography has been used to measure the viscosity of pure liquid Fe at high pressure and temperature in a large volume press. A probe sphere rising through liquid Fe at high pressure and temperature is imaged, in situ, allowing for the derivation of sample viscosity through a modified form of Stokes’ equation. The effect of pressure on viscosity is fit by the semi empirical f...
متن کاملPressure dependence of melt viscosity in the system NaAlSi3O8-CaMgSi2O6
The effect of pressure on melt viscosity was investigated in the system NaAlSi3O8-CaMgSi2O6 (Ab-Di) at pressures from 0.1 to 400 MPa using a parallel plate viscometer. The new measurements in the high viscosity range of 10 –10 Pa·s are consistent with previous data obtained at higher temperature (lower viscosity) in that the pressure dependence changes from positive for the polymerized Ab melt ...
متن کاملChemical diffusion of fluorine in jadeite melt at high pressure
The chemical diffusion of fluorine in jadeite melt has been investigated from 10 to 15 kbars and 1200 to 14OO“C using diffusion couples of jadeite melt and fluorine-bearing jadeite melt (6.3 wt.% F). The diffusion profile data indicate that the diffusion process is concentration-independent, binarv. F-O interdiffision. The F-O interdiffusion coefficient ranges from 1.3 X IO-’ to 7.1 X lo-’ cm*/...
متن کاملTransport properties of carbonated silicate melt at high pressure
Carbon dioxide, generally considered as the second most abundant volatile component in silicate magmas, is expected to significantly influence various melt properties. In particular, our knowledge about its dynamical effects is lacking over most of Earth's mantle pressure regime. Here, we report the first-principles molecular dynamics results on the transport properties of carbonated MgSiO3 liq...
متن کاملEffects of water and fluorine on the viscosity of albite melt at high pressure: a preliminary investigation
The viscosities of fluorineand water-bearing melts based on albite composition have been determined at 7.5, 15 and 22.5 kbar by the falling-sphere method. All melt viscosities decrease isothermally with increasing pressure. At 12000( ` the vi~osity of the fluorine-bearing melt (albite + 5.8 wt.C~ fluorine substituted for oxygen, denoted AbF, O n) decreases from 5000 + 750 P at 7.5 kbar to 1600 ...
