AN OPTICAL CELL FOR RAMAN SPECTROSCOPIC STUDIES OF SUPERCRITICAL FLUIDS AND ITS APPLICATION TO THE STUDY OF WATER TO 500°C AND 2000 BAR

Frantz J.D.; Dubessy J.; Mysen B. (1993)

A high-temperature, high-pressure optical cell has been developed for the study of aqueous solutions by Raman spectroscopy. The disk-shaped cell has a sample volume of < 1 ml and utilizes diamond or sapphire windows set ...
ENSTATITE-FORSTERITE-WATER EQUILIBRIA AT ELEVATED TEMPERATURES AND PRESSURES

Zhang Y.G.; Frantz J.D. (2000)

The compositions of aqueous fluids in equilibrium with enstatite + forsterite were investigated at temperatures from 900 to 1200°C and pressures from 1.0 to 2.0 GPa. Experiments, performed in a piston-cylinder apparatus, ...
HIGH-TEMPERATURE RAMAN SPECTROSCOPIC STUDY OF H2O-CO2-CH4 MIXTURES IN SYNTHETIC FLUID INCLUSIONS: FIRST INSIGHTS ON MOLECULAR INTERACTIONS AND ANALYTICAL IMPLICATIONS

Dubessy J.; Moissette A.; Bakker R.J.; Frantz J.D.; Zhang Y.G. (1999)

Raman spectra of fluids of the CO2-CH4-H2O systems contained in synthetic fluid inclusions have been obtained above the homogenization temperature to 500°C. Spectra of the CO2 and CH4 gases do not vary along the portion ...
RAMAN SPECTRA AND STRUCTURE OF BAO-SIO2, SRO-SIO2 AND CAO-SIO2 MELTS TO 1600°C

Frantz J.D.; Mysen B.O. (1995)

Raman spectra were collected for barium silicate, strontium silicate and calcium silicate melts at temperatures ranging from the glass transition region to temperatures as high as 1600°C. For melts less polymrized than ...
RAMAN SPECTRA OF POTASSIUM CARBONATE AND BICARBONATE AQUEOUS FLUIDS AT ELEVATED TEMPERATURES AND PRESSURES: COMPARISON WITH THEORETICAL SIMULATIONS

Frantz J.D. (1998)

One-molal solutions of potassium carbonate and potassium bicarbonate were investigated by Raman spectroscopy from 22° to 550°C and from 1000 to 2000 bar. Experiments were performed in a special hydrothermal pressure vessel ...
SALTS OF ALIPHATIC CARBOXYLIC ACIDS: RAMAN SPECTRA AND ION PAIRING IN HYDROTHERMAL SOLUTIONS CONTAINING SODIUM AND CALCIUM ACETATES

Frantz J.D. (2000)

A 2.0 molal solution of sodium acetate and 0.1, 0.5, and 1.0 molal solutions of calcium acetate were investigated by Raman spectroscopy from 22 to 400°C at 1000 and 2000 bar. Experiments were performed in a special ...
