Journal ArticleDOI
Determination of the homogenization temperatures and densities of supercritical fluids in the system NaClKClCaCl2H2O using synthetic fluid inclusions
Yi-Gang Zhang,John D. Frantz +1 more
TL;DR: In this paper, the homogenization temperatures of the synthetic fluid inclusions were analyzed by micro-thermometry, and the results of these experiments compare favorably to previously published ones; however, they do not consider solutes containing more than one solute.
Journal ArticleDOI
Raman spectroscopy of silicate melts at magmatic temperatures: Na2O1bSiO2, K2O1bSiO2 and Li2O1bSiO2 binary compositions in the temperature range 25–1475°C☆
Bjorn O. Mysen,John D. Frantz +1 more
TL;DR: In this paper, high-quality Raman spectra of silicate glasses, supercooled liquids and liquids have been obtained in situ to temperatures of 1475°C by focussing the diameter of the exciting laser beam to ∼ 1 mm, and to control the depth of focus in the sample to 6-40-μm depth.
Journal ArticleDOI
An optical cell for Raman spectroscopic studies of supercritical fluids and its application to the study of water to 500°C and 2000 bar
TL;DR: In this article, a high-temperature, high-pressure optical cell has been developed for the study of aqueous solutions by Raman spectroscopy, which has a sample volume of < 1 ml and utilizes diamond or sapphire windows set at 90° to one-another.
Journal ArticleDOI
Raman spectra of potassium carbonate and bicarbonate aqueous fluids at elevated temperatures and pressures: comparison with theoretical simulations
TL;DR: In this paper, Raman spectroscopy of one-molal solutions of potassium carbonate and potassium bicarbonate was performed in a special hydrothermal pressure vessel fitted with conical diamond windows.
Journal ArticleDOI
The compositional limits of fluid immiscibility in the system H2ONaClCO2 as determined with the use of synthetic fluid inclusions in conjunction with mass spectrometry
TL;DR: The compositional limits of fluid immiscibility in the system NaClH2OCO2 were investigated from 500° to 700°C at pressures of 1, 2 and 3 kbar.
