The effect of oxygen fugacity, melt composition, temperature and pressure on the oxidation state of cerium in silicate melts

Berry, Andrew; Burnham, Antony D


Ce LIII-edge X-ray absorption near edge structure (XANES) spectra were recorded for a series of synthetic glasses prepared over a range of oxygen fugacities (fO2s, from -10 to +11 in logarithmic units relative to the quartz-fayalite-magnetite, QFM, buffer), temperatures (1300-1500°C), and pressures (1atm and 1GPa). The oxidation state ratio of Ce, Ce4+/∑Ce (where ∑Ce=Ce3++Ce4+), was determined from the spectra allowing the relationships between Ce4+/∑Ce and fO2, temperature, pressure and melt...[Show more]
