The effect of fluoride on the Fe2+/Fe3+-redox equilibrium in glass melts in the system Na2O/NaF/CaO/Al2O3/SiO2

Effect of CO Pressure Gradients on the Photochemistry and Thermal Chemistry of Fe(CO)5 Physisorbed into Porous Vycor Glass

“…Since oxidation of Fe 0 by either O 2 or adsorbed water depends on [H + ], the extent of oxidation in silica matrices may reflect the pH of the different silica surfaces on which it occurs . To a significant extent, surface pH reflects the method of preparation of the silica matrix and the thermal history of the sample . The pH of the PVG surface, for example, is between 4 and 5 …”

Evaluation of voltammetric redox potential for Fe3+/Fe2+ in silicate liquids

“…(5) The E1/2 (SLS) of the present study is agree with that reported by previous voltammetry measurement at fO2 = 1 and 0.21. 12) (6) The E1/2 (SLS) at 1655 K and E1/2 (DiAn) at 1680 K can be approximated by equations (14) and ,…”

Effects of composition on redox behaviors of antimony or arsenic ion in silicate melts by differential pulse voltammetry

“…This is the reason why electrochemical techniques developed in aqueous solution are applied to high-temperature glass melts. There are so many reports on redox states of multivalent ions in glass melts using cyclic voltammetry [8][9][10], square-wave voltammetry [2,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27], and differential pulse voltammetry [6,10,[28][29][30][31][32][33][34]. Among these papers, Rüssel and co-workers [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] reported the redox states, the equilibrium constants, and thermodynamic data of various types of multivalent ions in some glass melts by using square wave voltammetry.…”
