Iron oxide-alloy equilibration experiments were conducted in H2 -CO2 gas mixtures at 1 atm and 1125–1240 °C using strips of Au74Pd26 (wt%) and produced Au-Pd-Fe alloys with 0.03–13 wt% iron. ...
Thermodynamic parameters and sorption of U(VI) on ACSD     thermodynamic parameters  sorption  U(VI) on ACSD       font style='font-size:12px;'> 2011/11/10
Abstract This paper discusses the sorption properties for U(VI) by alginate coated CaSO4·2H2O sepiolite and calcined diatomite earth (Kieselguhr) (ACSD). The removal of U(VI) from aqueous solution by...

For iron-rich compositions, reactions among titanite, clinopyroxene, olivine, quartz,magnetite, and ilmenite can constrain the conditions under which common rocks form.Phase equilibrium experiments in...
The Gibbs free energy (DG ) of the reaction kaolinitedickite was generated from 0(1) solubility measurements of natural kaolinite and dickite performed in acid solutions at temperatures ranging from...
The heat capacities of synthetic coesite and jadeite were measured between about 15 and 850 K by adiabatic and differential scanning calorimetry. The experimental data were smoothed and estimates were...
Spontaneous strains for the a ↔b transition in quartz were determined from lattice parameter data collected by X-ray powder diffraction and neutron powder diffraction over the temperature range ...

Abstract: The thermodynamic cationic exchange process involving divalent (Cu, Zn, Cd, Hg, Pb and Ca) and monovalent (Na) cations in Brazilian red Latosol soil was studied. Using a batchwise method, th...
At present the most widely used models of thermodynamic mixing properties of garnet are those that are optimized to fit the experimental phase-equilibrium data along various binary garnet joins usin...
High-temperature volumes of K-Na mixing have been investigated for a seven-member low albite-microcline ion-exchange series by conducting X-ray powder diffraction mea- surements from room temperatur...
The heat capacity ofa three-phase sample ofFeo.99o:to.oosO,Fe304, and Fe(mole fractions 0.915, 0.078, and 0.007, respectively) has been measured byadiabatic shield calorimetry at temperatures from 13 ...
Weperformed in-situ Raman spectroscopy and X-ray diffraction experiments at high temperature and ambient pressure to investigate the intrinsic anharmonic properties of {J-Mg2Si04and the mechanism and ...
